Classifying cloud type is an important task for global cloud climatology studies. Different types of clouds are governed by different cloud dynamical processes and have different microphysical properties, which can result in quite different cloud radiative forcings. Because cloud type corresponds to specific cloud physical properties, cloud classification is also needed to apply other algorithms to derive quantitative cloud content and radiative data. 2B-CLDCLASS classifies clouds into either stratus (St), stratus (Sc), cumulus (Cu, including cumulus congestus), nimbostratus (Ns), altocumulus (Ac), altostratus (As), deep convective (cumulonimbus), or high (cirrus and cirrostratus) clouds, based on different rules for hydrometeor vertical and horizontal scales, the maximum Ze measured by the CPR, indications of precipitation, and ancillary data including ECMWF predicted temperature profiles and surface topography height.
