JPSS NOAA Visible Infrared Imaging Radiometer Suite (VIIRS) Cloud Top Pressure (CTP) Environmental Data Record (EDR) from IDPS

VIIRS-CTP-EDR

browse graphicExample of VIIRS Cloud Top Pressure EDR taken over the United Kingdom on May 8, 2016.
This dataset contains a high quality operational Environmental Data Record (EDR) 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). The algorithm retrieval utilizes VIIRS channel brightness temperatures and reflectances. Inputs required to develop the CTP algorithm include other VIIRS Retained Intermediate Products (RIPs) such as Cloud Optical Properties (COP), Cloud Top Parameters (CTP), Perform Parallax Correction (PPC), Cloud Cover and Layers (CCL), Cloud Base Height (CBH) and Generate Cloud EDRs (GCE). The RIPs are 750 meter spatial resolution products and the output EDRs are gridded to 6 kilometer resolution. The EDR provides global coverage approximately every 12 hours. By default, IDPS VIIRS CTP data obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed in four 86-second granules in Hierarchical Data Format v.5 (HDF5) with metadata attributes included.
