Wow -- Satellites are constantly scanning the Earth; these illustrations in real-time are quite accurate.

I'm old-school, I stick to my old maps. It's almost too much information for me to look at, however the satellite data, radiosonde data, and surface temperatures are compiled into weather & reanalysis models as initial conditions before they run the equations of motion forwards or backwards in time.

This is what Joe Bastardi speaks of when he looks at 'global temperatures' (in particular the CFSv2 from NCAR, where CFSv2 = version 2 of Climate Forecast System). The CFSv2 is what NCEP/NCAR uses to create reanalysis data. Europeans (ECMWF) have their own.

You can see the large discrepancies between NCEP's own model with NASA & NOAA surface temperature global data (which is hacked together and adjusted), where the last 10 years were actually cooling until the recent El Nino spike. The plot below comes from averaging data in the plots you linked to, which are well done!

Thanks for sharing; I'm bookmarking that.
