NOAA JPSS Visible Infrared Imaging Radiometer Suite (VIIRS) Cloud Base Height (CBH) Environmental Data Record (EDR) from IDPS
VIIRS-CBH-EDR
This dataset contains a high quality operational Environmental Data Record (EDR) of Cloud Base Heights (CBH) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS). CBH is defined as the height above sea level at which cloud bases occur and is derived by subtracting Cloud Optical Thickness (COT) values from Cloud Top Height (CTH) values. The algorithm also incorporates data from the Cloud Mask Intermediate Product (IP). Each square cell is an average of reported base heights within that cell. If a cloud layer occupies only a portion of the cell then the average is reported for only the portion of the cell covered by the cloud. The spatial resolution of the EDR is 6 km and data are collected during day and night passes which provides global coverage at a temporal resolution of approximately every 12 hours. By default, VIIRS CBH IDPS data obtained from the Comprehensive Large Array-Data Stewardship System (CLASS) are distributed in four 86-second granules in Hierarchical Data Format V. 5 (HDF5) with metadata attributes.
