Weisz, E, Li, J, Menzel, WP, Heidinger, AK, Kahn, BH, Liu, CY (2007). "Comparison of AIRS, MODIS, CloudSat and CALIPSO cloud top height retrievals". GEOPHYSICAL RESEARCH LETTERS, 34(17), L17811.

Knowledge of cloud properties like cloud top height (CTH) is essential to understand their impact on the earth's radiation budget and on climate change. High spectral resolution measurements from the Atmospheric Infrared Sounder (AIRS) are well suited to reveal valuable information about cloud altitude. The CTH retrievals derived from AIRS single field-of-view(FOV) radiance measurements are compared with the operational MODIS ( Moderate Resolution Imaging Spectroradiometer) cloud product, and Level 2 products obtained from radar and lidar instruments onboard the EOS (Earth Observing System) CloudSat and the CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation) satellites. Two cases containing a variety of cloud conditions have been studied, and the strengths/shortcomings of CTH products from infrared (IR) sounder radiances are discussed.
