  9. AIRS / MODIS comparisons using Tb histograms Nov 21, 2002 • Approach using Aqua MODIS and AIRS granule data • convolve AIRS spectra from AIRS granule 196 with MODIS SRFs • Compute Mean and variance of MODIS observations within each AIRS FOV. (AIRS FOVs currently represented as circles, as with the condensedMODIS cloud algorithm). • Screen data based on cloud flag, MODIS variability, scan angles, and compare observed brightness temperatures
