There is no her’s, no hi’s, no it’s.

It’s is a contraction of it is.

The two wire connection is probably a 4-20ma current loop. That would take out wire resistance. Too old a design for digital data riding on top of power. Still, a thermistor is a lousy way to measure temperature. They drift with time and calibration is a pipe dream. OK for controlling temperature where absolute accuracy doesn’t matter (think fish tank heater) but not good at all for research.

UHI effect has to depend on wind patterns. If you had a huge array of temperature sensors, you would see an elevated temp envelope around the heat collector/generator. With only a few sensors, not even a SWAG. You cannot separate random from systemic effects. Correction factors are blue sky.

Seems like an ideal way to bet the future of the economy. (NOT)

As if there will be only one cause of the temperature change over time… start looking at all of your bases… this is an Oregon station so it will be affected by changes in PDO (check for step changes related to PDO). It looks like it is also a reverse ENSO location (El Nino causes cooling here… look at 98)… then look at equipment, urbanization / microclimate / irrigation issues and etc.

The closest I’ve been to that type of terrain was Ft Irwin, and driving through So Cal and Arizona a couple times (Bakersfield, Needles, Tehachapi area)

Those trees look 30 to 40 years old to me, which means they were planted around the time the upward temperature trend started.

Those trees/shrubs will be irrigated to get them to grow and that’s probably your answer – increased humidity from irrigation and transpiration.

Perhaps I’m confusing annual with monthly and daily mean. High annual mean, in the chart is (about) 1922. “Highest” (in 1933) you refer to must be a daily.

I have 3 more to report.
1) New Hamphsire on the Mass. border on US 93 at the “Welcome to NH”
rest area. The station is a few feet from the largest, busiest road in
the state. Large electronics box under the temperature station.

2) University of Massachusetts, Lowell. Station is mounted on a pole
on the roof at the junction of 2 roofs. Heated by 2 roofs, AC units, and
a large wall, the temp. station is about 30′ off the ground.

3) Brunswick Naval Air Station, Brunswick Maine. Good location in a
field far away from buildings and pavement.

All are visible from Google Earth; I have recent shots for 1 and 2.
NASB will not let civilians on the flight line to take pictures of 3, so no
photos of that one.

Re: “The highest temperature ever recorded in Mina was 110 °F in 1933…”

Was the peak temp in ’23?

I’m from a town 30 miles west of Mina (Hawthorne) and while there are some rocks in the valley, large ones like those situated near the MMTS aren’t prevalent unless you try to dig up something in your yard or are walking along a gully. If you look at the first picture facing east, you’ll see what the terrain is like in most any direction throughout the region. It’s sagebrush, desert grass and tumbleweeds. There are some widely scattered rocky areas, but mostly you find those in and along the mountains. In the summer, large rocks like those in the picture get extremely hot and would undoubtedly act as a heat sink.

And the cable issue made me go look it up… The NOAA CO-OP site has a photo of a two-conductor cable. Because the MMTS is described as a thermistor, either the MMTS display is measuring the thermistor directly (probably as a resistance through the cable), or both power and serial data are being sent through one pair of wires. However it works, “Sensor Cable Max Distance = 1/4 mile” suggests that trenching efforts are probably a significant cause of sensors being near buildings.

Maybe the NOAA should supply trenching tips such as this collection (the E-Z Trencher link has moved from .htm to this .php URL).

Everytime you see an article about some species struggling to survive there is somehow a tie in to AGW. This one actually sites “chilly temperatures” as the probable cause.

Nasty fungus may be killing thousands of bats
By Will Dunham Will Dunham – Thu Oct 30, 4:06 pm ET Reuters

WASHINGTON (Reuters) – A previously unknown fungus that thrives in chilly temperatures may be the culprit behind the deaths of at least 100,000 bats hibernating in caves in the northeastern United States, scientists said on Thursday.
