NOAA JPSS Advanced Technology Microwave Sounder (ATMS) based Tropical Cyclone (TC) Products from NDE

The JPSS Microwave Sounder-based Tropical Cyclone (TC) Products provide estimates of tropical cyclone maximum wind speed, minimum sea level pressure, radii of 34, 50, and 64 knot winds in 4 quadrants relative to the storm center, and balanced horizontal winds from 1000 to 200 mb within 600 km of the storm center. The product includes two output data types: 1) ATMS Tropical Cyclone Wind Products Radial/Height Cross Sections (RZA), and 2) ATMS Tropical Cyclone Wind Products Gridded Heights (XYA). Coverage is in six Global tropical cyclone basins, with a 6 x 6 degree domain centered on each active tropical cyclone. Spatial resolution is a 0.2 degree latitude/longitude grid for the balanced winds, and a point resolution for the intensity/radii. Temporal resolution is every 6 hours, roughly 3 hours after meteorological synoptic time. The number of products produced per year depends on the number of tracked storms and their duration. Basin identifiers are determined by the location of the storm when it first forms and storms maintain that basin classification even if they travel into other basins. The product was developed by the NOAA/NESDIS Center for Satellite Application and Research (STAR) and is produced operationally at the NOAA/NESDIS Office of Satellite and Product Operations (OSPO). It is distributed in netCDF-4 file format with metadata attributes included.
