Sentences with phrase «giss land surface air temperature»

Animation 1 compares the GISS land surface air temperature trends to UAH lower troposphere temperature trends over land for the period of 1979 to 2012.

However, the CRU global mean combined land air / sea surface temperature estimates for Jan - Aug 2005 lag behind the 1998 annual mean estimate by 0.08 C (0.50 C vs. 58C for 1998) while GISS indicates a lag of 0.02 C.

So the infilled GISS data, which extends out over the Arctic, would show the greater warming since the 1970s... until the warming stops for Northern Hemisphere sea surface temperatures and for the low - to - mid latitude land surface air temperatures.

This is likely caused, in part, by GISS masking sea surface temperature data in the polar oceans and replacing it with land surface air temperature data, which is naturally more volatile.

Blue points: the GISS 1999 land + sea global surface air temperature record.

Cowtan and Way argued several years ago that much of the apparent discrepancy in trends at surface arose because the most common temperature series (HadCRUT4, GISS etc) spliced air temperature over land with sea surface temperatures.

Figure 6 shows the global land surface air temperature plus sea surface temperature anomalies (average of GISS LOTI, HADCRUT4 and NCDC datasets, like The Escalator) before, during and after the 1997/98 El Niño.
