This paper compares the calibration consistency of the spectrally-matched thermal emissive
bands (TEB) between the Suomi National Polar-orbiting Partnership (S-NPP) Visible
Infrared Imaging Radiometer Suite (VIIRS) and the Aqua Moderate Resolution Imaging
Spectroradiometer (MODIS), using observations from their simultaneous nadir overpasses
(SNO). Nearly-simultaneous hyperspectral measurements from the Aqua Atmospheric
Infrared Sounder (AIRS) and the S-NPP Cross-track Infrared Sounder (CrIS) are used to�…

The S-NPP Visible Infrared Imaging Radiometer Suite (VIIRS) instrument is built with strong
heritage from EOS MODIS, and has very similar thermal emissive bands (TEB) calibration
algorithm and on-board calibrating source-a V-grooved blackbody. The calibration of the two
instruments can be assessed by comparing the brightness temperatures retrieved from
VIIRS and Aqua MODIS simultaneous nadir observations (SNO) from their spectrally
matched TEB. However, even though the VIIRS and MODIS bands are similar there are still�…
