Minnis Cloud Products Using Visst Algorithm (VISST) - IOP
Instrument Categories: Cloud Properties, Satellite Observations
General Overview
Satellite based retrievals of cloud and radiation properties are available in this value-added product provided by Pat Minnis' group at NASA/Langley using the VISST (Visible Infrared Solar-Infrared Split Window Technique) algorithm. These datastreams are both pixel-level (4-km) retrievals and averages on a 0.3 or 0.5 degree latitude-longitude grid and replace earlier satellite-based retrievals on the Layered Bispectral Threshold Method (LBTM). For more details, see the External Data Center web page.
