Product Description:
The Level-2 Continuity Atmosphere Cloud Property Products consists of cloud optical and physical parameters. These parameters are derived using remotely sensed infrared visible and near infrared solar reflected radiances.  Infrared channel radiances are used to derive cloud top temperature cloud top height effective emissivity cloud phase ice vs. water opaque vs. nonopaque and cloud fraction under both daytime and nighttime conditions. Visible radiances are used to derive cloud optical thickness and effective particle radius and cloud shadow effects. Near infrared solar reflected radiance provides additional information in the retrieval of cloud particle phase ice vs. water clouds vs. snow.  All gridded cloud parameters are stored as Scientific Data Sets (SDS) within the file. Nighttime files are smaller than their daytime counterparts since only cloud top properties are retrieved at night. The Continuity Atmosphere Cloud Products will be used to investigate seasonal and interannual changes in cirrus semitransparent global cloud cover and cloud phase with multispectral observations at high spatial 1 kilometer resolution. .
