surfacestations.org is back online and there are some good improvements in layout. In the page directory for each state, there are now thumbnails for the stations with information. New stations are coming in all the time. Today’s tide brought in another interesting Washington site from Gary Kobes – Long Beach WA (454748; 72791002). Its physical appearance is pretty good as these things go – maybe a little near the road, but in a rural area.
Here’s a thumbnail – go to the site for the portfolio.
So what does the temperature history look like? Does this rural site show the powerful 20th century temperature increase that we see at sites like Phoenix Airport, Fresno Airport and even “rural” sites like Marysville and Petaluma? I’m afraid that you can guess the answer.
Here is a plot of the USHCN, GHCN and GISS versions (7 in all) of the station history (in anomaly deg C). In this case, there is no trend, although there is pronounced multidecadal variation. While the information to date is not sufficient to assess the impact of microsite problems, there does seem to be a pattern in which sites that are in poor compliance with WMO standards tend to have much more pronounced trends than sites that are in relatively good compliance (as with Orland and Marysville that originated the surfacestations.org inquiry.)
In this case, adjustments are not severe. USHCN, GHCN and GISS adjustments are shown in the three following figures.
