Comparison of LST from AIRS and MODIS from the EOS Aqua platform

Level 3 gridded global land surface products from the EOS Aqua AIRS and MODIS sensors are compared over a 12 month period beginning January 2003. Monthly mean land surface temperature estimates from the Aqua AIRS sensors at 1 degree spatial resolution are compared with the corresponding estimates from the Aqua MODIS sensor averaged over the same spatial domain. Global differences maps in land surface temperature have been produced at 1 degree spatial resolution along with time series plots of the monthly AIRS and MODIS differences for selected geographic regions. Preliminary evaluation of these product differences will be investigated using detailed case studies.
