Analysis of concurrent space based and ground based atmospheric infrared spectrometer measurements

Infrared spectrometer data from the space-based downward looking NASA Atmospheric Infrared Sounder (AIRS) and from the ground-based upward looking Atmospherically Emitted Radiance Interferometer (AERI) are used in this study. Spatially and temporally concurrent cloud free data from these spectrometers are correlated, analyzed, and compared to MODTRAN®5 simulated data. The effects of optical depth, water vapor, ozone, carbon dioxide, and methane on infrared remote sensing applications are characterized.
