| 説明 | The cross-sections above are from a granule in the Tropical Indian Ocean and show collocated CloudSat, CALIPSO, and AIRS cloud fields as a function of height. The images illustrate the ability of AIRS to resolve quantitatively meaningful cloud information. (a) CloudSat94 GHz reflectivity from the 2B-GEOPROF product. (b) CloudSat cloud confidence mask from the 2B-GEOPROF product restricted to cloud confidence values > 20. The 5 km CALIPSO cloud feature mask cloud top heights and bases are shown in black. The centers of the red circles show the AIRS V5 (up to) two layers of cloud top height and associated values of cloud fraction (smallest to largest circles are from 0 to 1, respectively). Likely unphysical cloud layers with cloud fraction < 0.01 are not included. (c) CloudSat cloud classification from the 2B-CLDCLASS product. (d) CALIPSO 532 nm total attenuated backscatter (colorized) and 5 km cloud feature mask cloud top heights and bases shown in white.CitationKahn, B. H., Chahine, M. T., Stephens, G. L., Mace, G.

Working in tandem, the two instruments make simultaneous observations all the way down to the Earth's surface, even in the presence of heavy clouds. With more than 2,000 channels sensing different regions of the atmosphere, the system creates a global, 3-dimensional map of atmospheric temperature and humidity, cloud amounts and heights, greenhouse gas concentrations, and many other atmospheric phenomena. The AIRS and AMSU fly onboard NASA's Aqua spacecraft and are managed by the Jet Propulsion Laboratory, Pasadena, California, under contract to NASA. JPL is a division of the California Institute of Technology in Pasadena.CreditNASA/JPL AIRS ProjectDownload the imageVarious sizes of the image are available, and there are two ways to download:1) Right-click on the image.
