>I don’t know of a global gridded surface air temperature product that is easily web-browse-able.

Aha. Thanks. So it seems if there is something then it is rather well hidden.

>I don’t know why some surface stations have been terminated. In general, I think the U.S. and Europe have been shutting down stations because they feel their meteorological network is oversampled and not worth the expense to maintain all of them. I suspect the Middle Eastern network is not as dense, so their reasons may be different.

Oversampled? If I look at the northern siberian region (Tazovsky District, Yamal Peninsula etc.) then on a first glance I see that out of four stations there is only
one anymore working (at least until 2012), namely Lesinko.

Cape Kharasovoy stopped in 2004, Vilkickogo and Gyda stopped in 2008.

BUT!!!!!!!!

If I only look at the temperature values of Gyda then this could send out a superalarm:

Within a time window of 20 years (1988-2008) the temperature anomalies are going up from like June -0.50 to 0.60, July -1.95 to 2.20, August -0.8 to 3.60, September -0.45 to 2.90 etc. !
