Tim Channon comments about the temperature adjustments at Luling:
Some of the Luling observer sheets are online at the Lulling farm web site. I assume this gives independence from NCDC and is therefore the original.
Picking up one I archived online, Jan 2011, calculated the mean by hand.
I make it 8.11C
First sheet you show 899E
Second sheet 893E
Oh what fun.
This is confirmed by the station record.
The mean measured was 46.6F, = 8.11C.
As Tim points out, the USHCN version was 8.99C on Friday.
And this has now morphed into 8.93C today.
Come back tomorrow, and I have no doubt it will have changed again.
Apparently this is “good science.”
