Luling Update

NOT A LOT OF PEOPLE KNOW THAT

By Paul Homewood

Further to yesterday’s post on the massive temperature adjustments, made by USHCN, at Luling, Texas, there is some more information on the station location there.

Nick Stokes has commented:

I looked into this. The BEST analysis is here.

It seems that there was a station move in May 2011, and an almost immediate drop in temperature relative to the regional average of over 1°C. It looks like the USHCN algorithm is using the regional average until it can get a handle on the effect of the move. So of course the “adjustment” looks large.

So, I have taken a closer look at the station metadata, as supplied by NOAA.

It would appear that the current site, marked in blue, has moved by about 100 yds, although the altitude has been unchanged at 400 ft, hardly enough to cause the 1C change, which Nick suggests.
