Project: CALIPSO

The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center in collaboration with the CALIPSO mission team announces the release of a new CALIPSO IIR level 3 (L3) Global Energy and Water cycle Experiment (GEWEX) Cloud product. This new data product is a reformatted version of CALIPSO’s contribution to the GEWEX cloud assessment of global cloud datasets from satellites ( The files include global distributions of clouds microphysical properties along with cloud amount, radiative temperature, effective emissivity, and cloud optical depth as averages and histograms on a uniform 2-dimensional (2D) spatial grid. All level 3 parameters are derived from the CALIPSO IIR version 4.2 level 2 products, with a temporal averaging of one month.
