WUWT readers who have followed this blog and the surfacestations.org project for a long time know that the USHCN climate station of record in Marysville, California, is the station that gave me that moment “when the light bulb went on”. I still remember my cellphone conversation (shortly after surveying the site) with my friend Russ Steele, saying:
“Russ you won’t believe it, they are measuring the temperature of a parking lot!”.
Some of the pictures I took that day are below, I’ve annotated them to point out things of interest.
I made Marysville the very first of the “How not to Measure Temperature” series on May 26th, 2007.
I realized in discussions at this Climate Audit thread, since Marysville was one of the first stations I surveyed, I hadn’t looked at the metadata for it in almost two years. Time for a look again given the discussion of this thread. I’ve been busy chasing hundreds of other stations but haven’t looked back to that one where I had the light bulb go on.
I found some interesting things last night in the NCDC Metadata (MMS) for Marysville at http://mi3.ncdc.noaa.gov/mi3qry/login.cfm (use guest login button)
First in The UPDATES Tab
[2009-02-04] 9999-12-31 2009-02-04 MSLAGLE AD HOC NONE — CLEAN UP OF COOP-A STN TYPE ISSUE MSLAGLE 2009-02-04
Then this in the REMARKS Tab
[2008-07-01] 9999-12-31 GENERAL REMARK REASON: UPDATE PUBLICATION; DATA NO LONGER PUBLISHED. DATA ONLY GOES TO WFO/STO. DATA THAT IS RECIEVED FROM THIS STATION WILL BE USED AS BACK UP TO TO MARYSVILLE AIRPORT DATA (04-5388) WHICH IS NOW BEING PUBLISHED. — INGEST_USER 2009-02-10
It seems to me like they gave up on it. There is not much that can be fixed there in terms of siting like they did at Detroit Lakes. Marysville Fire Station property is 98% Asphalt/concrete/buildings, with a small patch of grass in the front by the street/sidewalk.
I decided to check the B91 Forms, and sure enough, NOAA bailed on Marysville in October of 2007, just a few months after I first brought it to national attention with “How not to Measure Temperature“
See the screencap of the NCDC B91 database showing the span of record:
It is sad really, a station with a long record, since Feburary 1897, climatically “out to pasture” after more than a century, likely a victim of lack of quality control by NOAA. That being said, why should we retain questionable station data in our climatic database?
Here is the very last B91 form submitted from the Marysville Fire Department in October 2007:
So I guess NOAA saw enough problems at Marysville to put it “out to pasture”. So now they use the airport.
Ironically, since the data from Marysville is now going directly to the NWS office in Sacramento/Stockton, rather than NCDC’s climatic database, the station mission has come full circle. It is likely now used for forecast verification, which is what the original mission of the COOP network was.
