Sentences with phrase «land surface air temperature»
"Land surface air temperature" refers to the measure of how hot or cold the air is just above the ground. It helps us understand the temperature of the air that we feel on land. Full definition

The UK Met Office has asked the World Meteorological Organization (WMO) to create a new state - of - the art dataset of global land surface air temperatures for improved climate diagnostics.
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.
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.
Today a new set of fundamental holdings of land surface air temperature records stretching back deep into the 19th Century has been released as a result of several years of effort by a multinational group of scientists.
Further, we are key players in an effort to transform and update our understanding of land surface air temperatures through the International Surface Temperature Initiative [described in a recent paper, «Guiding the creation of a comprehensive surface temperature resource for twenty - first - century climate science.»
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.
