Weather station ‘X’

A mystery for you.

This weekend (weather permitting) Willis and I will be visiting the location of this weather station in the USA. Can you guess where it is? I can assure you it is not the schoolhouse at Bodega nor is it Alfred Hitchcock’s summer house.

Note the Stevenson screen housing the thermometer to the left of the path. Click for a much larger image.

The interest for this station is that this particular station might have a very pristine record unblemished by UHI and other man-made encroachments. What we don’t know yet is if it is continuous record since the station was installed.

  1. I be happy that you two be havin’ an adventure together. (an’ be hopin’ you find the post’s grammatical error.)

    [we be fixing it -mod]

  2. I’m not American, so it could be anywhere coastal, or an offshore island, judging by the low grasses and the fact the only tree is in the shelter of the house. I can’t see an anemometer mast (unless that’s it up against the house, in which case the readings would be awful). The screen is too close to the house, too. If it’s been this way for a long time the record would be OK, but the house looks fairly recent.

  3. Randall already nailed it.
    but more precisely:

    Farallon National Wildlife Refuge
    1 Marshlands Rd, Fremont, CA 94555
    N37.698244, W123.003355

    Have fun.
    But Watch out for Billionaire Tom Steyer’s big big yacht belching diesel soot in your row boat.

  4. “…might have a very pristine record…” yeah, but is it pristine from seagulls? Bird-poo heat radiation is ….

    /stupidity off…. resuming normall transition :)

  5. Boy you guys are quick. Saw it on my phone and recognized it as the research center on South Farallon Islands. By the time I got to log on to my computer to check and add a comment you guys already got it……

  6. There might be bird-made encroachments (or coatings) here. Is surface condition of the screen likely to be a feature of this record?

    If so, it’s likely to have added about 0.7 degC. I can just feel it in my waters.

  7. Should be a good day for whale watching. Make sure to have a camera ready on the boat ride.

  8. Ah – I see some others already got it. Hope you have a great wee excursion Anthony and Willis.

  9. The sixth place decimal-degree coordinates for your target weather station are:
    N37.698119, W123.003536

  10. The seagulls caught my attention. Have a lot of them where I live. When it is NOT raining you can watch the seagulls on the grass verges near the road. They do a little dance, patter their feet rapidly on the grass, this seems to fool the worms into thinking it IS raining, pop their heads up for a look see and become lunch. :-)

  11. NOAA data on Farallon has no data, but here are the ID’s:

    NESDIS ID 15CCE6A4 NWS Location ID FNDC1
    Location FARALLON ISLAND NEAR SAN FRANCISCO
    Latitude N 37°41’54” Longitude W 123°00’06” HSA MTR State CA
    Owner NWSWRH Channel 142 Initial Transmit Time (HH:MM:SS) 00:17:20

  12. Here is a history page. The Weather Bureau ran a station there from 1902-1913. GHCN Daily has it as USC00048376 and has some precip etc data from 1948-1951, but no temp.

  13. P.S. we need a selfie of you and Willis at the wx station with a Seagull on your shoulder.

  15. @Streetcred, LOL welcome to common core less. (btw those gulls did instantly remind me of Hitchcock)

  16. Richard111 wrote: “They do a little dance, patter their feet rapidly on the grass, this seems to fool the worms into thinking it IS raining, pop their heads up for a look see and become lunch. :-)”

    It is called pore pressure. The stamping of their webbed feet and weight induces liquefaction of the soil, the water pore pressure causes the soil to become liquid, just like when it rains and saturates the soil. The air and the owrms are forced to the surface…. lunch.

    And lunch is what Anthony and Willis will be if Farallon Asset Management Billionaire Tom Steyer sees them rowing in their little dinghy boat out to Farallon Islands, and Tom is in his 40 meter super-yacht. He’d ran flank speed and burn a kiloton of diesel to do in his #1 and #5 nemesis and chalk it up to climate change-induced “fog” for the Coast Guard.

    (sorry Willis, but you are at least #5. Anthony is #1, Curry is #2, JoNova, is #3, and Tisdale is #4.)

  17. No matter how many ways you cook it , sooner or later you would get sick of Seagull , still not far to go to the ‘shop’

  18. Based on the geology, flora and fauna (not to mention coastal view) I am guessing Bend, OR.

    • Interesting thread, the one on Stevenson screens. It’s not difficult to keep them painted, it’s not as if they have to be redone all that often if quality paint is used, and usually it’s touch-ups, not complete repainting. They’d certainly misread if NOT painted, but it’s equally important to keep them clean- they get covered in dust, urban pollution and bird droppings. Of more concern to me is changes in instrumentation over the years (from glass thermometers to electronic probes) and changes from large Stevenson screens to small ones. The old ones had room for clockwork autographic instruments such as thermograph and hair hygrograph. There are also practices such as leaving the bottle of water (for refilling the wet bulb muslins, especially in dry climates) inside the screen which might affect readings. There is also the “accuracy” or tolerance of the thermometers, which might be 0.3 degrees C with a smaller tolerance on the travelling instrument used to check that tolerance (hopefully twice annually). Given all the above it does make one wonder about the temperature record, but what else is there to rely on? Before the commencement of the satellite record, very little. Satellites need to be calibrated against ground instruments, too.

  19. Be sure to look into the function of those pipes along the sidewalk. I’m guessing probably for rain gutter runoff, but who knows. Looks like a really pleasant setting in any event.

  20. If you look closely, there’s a seagull (AKA sea rat) standing on top of the Stevensen screen. So not only do you have to consider the effect that seagull poop has on the radiative heat transfer characteristics of the screen (maybe a new category to consider under the Surface Stations project :) ) but you also have to consider radiative heating from sea rats perched on the screen.

    I think it would be a crappy job surveying this site. Call Mike Rowe for help. He lives in San Fran.

  21. I am in agreement with those who recommend you wear hats.

    “There are three kinds of people in the world:

    those that poop on people, those that are pooped on,

    and those that say, “Oh, look at all that poop!”

    :)

  22. “From 1902 to 1913, the former U.S. Weather Bureau maintained a weather station on the southeast island, which was connected with the mainland by cable. The results of the meteorological study were later published in a book on California’s climate. Temperatures during those years never exceeded 90 °F (32 °C) or dropped to 32 °F (0 °C).[15] Years later, the National Weather Service provided some weather observations from the lighthouse on its local radio station.”

    http://en.wikipedia.org/wiki/Farallon_Islands

  23. You might get to see some Great Whites leaping out of the water while attacking sea lions.

    Note: I sailed out of Alameda under the Golden Gate and out around the Farallon Islands in my Pacific Seacraft 37 in 1999/2000. It is expected to usually be a hull down bouncy sail.

    John

  24. Looks to me like it’s measuring the body temperature of an unladen seagull.

  25. Hmm. It seems a bad idea, to me, to put two such important people in a small craft travelling over the horizon, where the only witnesses would be; the CIA, the FBI, LAPD,
    the Secret Service, Homeland Security, US Coast Gaurd, US Border Service, US Navy, US Airforce, …. Are you travelling on US Weapons-Testing Day?

    SFPD or SF County Sheriffs.

    LAPD would be nearer Channel Islands.

  28. Isn’t this likely to simply have a sea-surface temperature? Virtually all the air around the screen will be directly from the sea. I guess this would still record the status of global warmiing.

  29. Okay, Anthony,

    Google Earth is a little fuzzy, but, if including the photo, adequate to the task. You’ve got a half-meter paved path ~6 m away. That comes to ~8 m.^2 or so. Then you have the house, ~155m^2, within 30 m. I noticed an odd stepping stone, but so long as that doesn’t add up to ~1 m^2 within 5 m., we are okay.

    So It’s a Class 2, Leroy (2010).
    I give you my official blessing.

    Using Leroy (1999), it’s Class 4 if including the path (“strict”), Class 3 if counting only the house. This is just like those stations I was joking about when we were saying “all Class 4 stations are created equal but some Class 4 stations are more equal than others”. Using Leroy (1999), it is Class 4. But using Leroy (2010), which actually measures the size of the heat sink, it is Class 2.

  30. “On the news tonight, we investigate the mysterious destruction of a weather station located in a remote nature preserve in California. All evidence points to a drone strike, but authorities have no idea who would have targeted the station or why. Watch more tonight at 11 on W.A.R.M. tv.”

  31. Thanks to everyone for the comments, it is indeed the South Farrallone Island weather station. I’m truly surprised that such a remote place was so quickly recognized.

    Unfortunately, it is not looking good for this trip:

    Willis is a seasoned mariner, me, not so much. But in a 25′ boat, no point in risking our lives for a weekend joyride. Earlier in the week, the forecast looked promising, now it worsens by the hour.

    But that’s the nature of forecasts, the closer you get to the target time, the more accurate they become.

  32. “But that’s the nature of forecasts, the closer you get to the target time, the more accurate they become.”

    So in AD 2100 the forecast by NOAA for that year’s global T will be 1.2 degrees C above the 20th century average?

  33. In case anyone is interested, in 2013 NOAA determined that the annual global combined land & ocean surface temperature was 0.62°C (1.12°F) above the 20th century average of 13.9°C (57.0°F). So my guess is 0.58°C warmer in 2100 than last year. Earth might then be just a few years into a warm phase, following the c. 2067-96 cool phase, following the c. 2037-66 warm phase, following the current 2007-36 cooling.

    I’m almost certain to be wrong, but also likely to be a lot closer to reality than the IPCC.

  34. Are we sure those gulls aren’t getting all broody on the thermometer bulb and trying to hatch it? What’s the temperature of a seagull’s butt? Watts up that gull?

  35. Thanks for an entertaining puzzle, Anthony. And I agree about the weather. When the report says “STEEP SHORT PERIOD SQUARED SEAS”, thats Coast Guard code a really ugly chop with vertical sides. And the problem gets very large right outside the Golden Gate.

    As with many such narrow passages to the sea, the channel under the Golden Gate Bridge is deep. But outside of the mouth, the silt load drops out, and there are shallows there. There’s a dredged ships’ channel, but the shallow spot north of the channel, called “The Potato Patch” by local fishermen, is prone to the occasional “sneaker wave” even on a nice day.

    But on a day with small craft advisories and the aforementioned “STEEP SHORT PERIOD SQUARED SEAS”, the whole mouth of the bay can get downright ugly. The waves bounce off the shore both north and south of the mouth of the Bay, and you get very confused seas coming from several directions, standing waves, strong cross currents. It’s what we used to call “Washing Machine Charley”, where you feel like you’re caught in said machine.

    So, it’s a day when as Anthony comments, there’s no point in being out there unless you have to … I’ve had to in the past, lack of money is a strong motivative force, but now, I have the luxury of not needing to.

    My best to all, especially Anthony,

    w.

    http://berkeleyearth.lbl.gov/stations/32529

    a while back Jones did a comparison marine air temps and coastal temps and land temps to address the UHI question.. Result: no evidence.

    there are piles of bouy data you can use to compare the trends in maritime air temp and nearby cities.

    but then you’ll also find that bouys differ from lighthouses and islands..and lighthouses differ from islands, and islands differ from rural and islands differ from urban

  39. I worked at a radio station that had a weather observation station in front. We took manual reading of the thermometer and precipitation every day. It had been at there for around 40-50 years. We actually got an award for being an observation station for so long from the NWS.

  40. Judging by the landscape and all those penguins this is obviously a photo taken during the ‘Ship of Fools’ daytrip that went wrong in Antarctica

    =====================================================================
    A couple of years ago I asked my local NWS about precipitation forecast. The answer i got was a bit detailed but what I took away from it was that for 4 to 10 days out the chance of precipitation refereed to the chance of precipitation anywhere in in the forecast area. 1 to 3 days out it referred to the percentage of the forecast area that would receive precipitation.
    Did I understand that right or should I dig out that old email and reread it?
    PS are those herring gulls in the picture?

  43. Well, Anthony, you can’t really cite this one for not receiving routine coats of “whitewash”. It’s probably caked on there several layers thick.

    Well, I guessed it was on the Farallon Islands, just from the rocky peaks; make that peaky rocks, and the seagulls. No idea, whereabouts in Mexico, Los Farallones might be.

    As for the distance between the screen, and the house. I defy anyone to identify from the Temperature records, or the temperature anomaly records, precisely when that house appeared on the scene.

    • I don’t know about US practice, but it’s usual here for weather stations to have frequent (every couple of years) skyline surveys which show whether buildings are encroaching on the observation area or nearby trees are growing overlarge. This then goes on the station file with other information such as dates of changes in thermometers (type, brand, serial number), plus their calibration data (every 6-12 months) plus addition (or subtraction) of equipment such as an anemometer mast or evaporation pan. All these instruments have siting requirements, such as an anemometer mast should be a minimum of 30 times the height of nearest building away from that building, but thin masts are OK.

    Well the “potato patch”, is actually an excellent demonstration, of the principles of wave “optics”.

    There are steep cliffs to the north and south, which reflect any waves coming into that region, and the result is you get interference of several wave patterns all at once. I have sat out there in the PP, in a 20 ft boat
    (offshore power boat) stationary, and watched the water in total amazement. It was quite impossible (on that occasion) to say which direction the waves were moving in. The pattern was a total standing wave pattern and the only direction water was moving, was vertically, straight up and down. No lateral movement of any kind of wave crest was discernible.

    That’s why, they call it “the dancing waters”. Now it is NOT always stationary standing waves. The sandy bottom shoals do impact it depending on; well damn near everything there is out there.

    It is a freaky place at times. I’ve never felt it was dangerous out there; but quite often, there is NO direction, and NO speed, at which it is comfortable, to run through there.

    So you just have to go in the direction you want, and pick a speed that your kidneys don’t object to.

    At other times, I have surfed through there as If I was at Waikiki beach. (in my boat). Quite spectacular. (and safe too)

  48. Mike T says terrestrial thermometers have to be calibrated against terrestrial thermometers. I thought that too, but Roy Spencer corrected me. Satellite platinum resistance thermometers calibrate themselves by reference to the known temperature of the cosmic background temperature, taken via mirrors.

    • Monckton of Brenchley, you are correct, except that it’s terrestrial thermometers calibrated against terrestrial, satellite using other methods (although believe there is some ground truthing of satellites against sea temperature data, for instance from drifting buoys).

    I agree with you Anthony with the forecasts, yet we get people like Gavin telling climate is not weather and yes they can use a computer program to tell us what the climate is going to be fifty years out. I consider that complete adult bovine fetal manner. Climate is the accumulation of weather events, weather is chaos you cannot predict a chaotic system out more than a few hours since the variables cannot be predicted. It would be like tell me in real dollars how much my house or the one that replaces it would be worth in fifth years. I would expect it to be more, the only thing for certain is I will be dead and gone by then. I could even be wrong about the latter since at this point and time most humans don’t get beyond 100 let alone one hundred and eleven, but medicine could have a break through on ageing but it highly unlikely, just like Gavin model and it many computer runs.

    Actually, there is one perched on the screen.

  54. Obviously with the usual flapping of all those seagull wings the temperature measured today would be somewhat cooler than in the past, so clearly all past temperatures will need to be adjusted down by a 97% consensus of Big Climate scientists to compensate. Being extremely busy with media and politician briefings, as well as grant submissions, naturally they’ll need to sub it out to Cook and Lewandowsky’s raters and no further correspondence will be entered into, in order to protect the privacy of the seagulls and sundry tertiary institutions.

  55. @Stevemosher are you really stating that the finest minds in climate science in universities couldn’t find UHI ? Really ? I did a GCSE geography project in England where we took temperatures in a village and outside of a village to demonstrate the UHI effect.

There are very few places, where it is reasonably safe to land, and it’s best to be with somebody, who actually knows where and how to do so safely. Quite apart from the fact, you are generally not allowed to. Was worth the run just to say I’d been out there. Furthest out I ever went in that boat, (out of Santa Cruz) was 75 miles; chasing albacore.

    As with many such narrow passages to the sea, the channel under the Golden Gate Bridge is deep. But outside of the mouth, the silt load drops out, and there are shallows there……”””””

    Actually, I never said any such thing.

    I believe you are citing something Willis posted; NOT me.

    nearby there is a bouy

    http://berkeleyearth.lbl.gov/stations/32529

    a while back Jones did a comparison marine air temps and coastal temps and land temps to address the UHI question.. Result: no evidence.

    there are piles of bouy data you can use to compare the trends in maritime air temp and nearby cities.

    but then you’ll also find that bouys differ from lighthouses and islands..and lighthouses differ from islands, and islands differ from rural and islands differ from urban

    Steven, I gotta say, once your algorithm gets done with it, I’m not surprised you find no UHI effect. Here is the record you cite, from the San Francisco Bay Buoy:

    Mean Rate of Change ( °C / Century )
    Raw monthly anomalies -3.55
    After quality control -3.19
    After breakpoint alignment -1.86
    Regional expectation during same months 0.72 ± 0.19

    Let me get this straight. It’s a buoy. Takes temperatures every hour. Has a gap in the data.

    The raw data is cooling fast, 3.55 degrees per century.

    After “quality control”, shockingly, it shows less cooling, 3.19°C per century.

    But then, after “breakpoint alignment”, meaning adjustment to better agree with the surrounding region, we’re down to a drop of 1.86°C per century. Funny how that works … seems to me I’d need a whole lot more evidence before I screwed with my own data that way.

    But in any case, even after “adjustment” the buoy record is cooling at nearly 2°C per century, and the “regional expectation” during that time is warming, not cooling but warming, at 0.7 ± 0.2°C per century.

    Hardly seems like a poster child for either your method or your claims about UHI … I’m not seeing the logic in the “breakpoint alignment”.
