Collocated observations of MODIS imager, CALIPSO Lidar and the CALIPSO Wide-field-of-view camera provide a means for investigating the occurrence of ice in stratiform clouds in a maritime environment. CALIPO near nadir viewing measurements are used to identify the specular reflectance signature indicative of oriented ice crystals. MODIS imager and spectral observations are used to classify the cloud type observed, as well as the pdf of the effective radius of the cloud field. The WFOV Camera also provides meteorological context. This presentation will discuss the frequency of occurrence of oriented ice crystals in particular low-level cloud structures in maritime conditions.
