Data Description

    Microwave Tropical Cyclone (MW_TC) - The NOAA/NESDIS 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. Estimates were derived from the Advanced Technology Microwave Sounder (ATMS) and Advanced Microwave Sounding Unit (AMSU). The product includes two output data types: 1) Tropical Cyclone Wind Products Radial/Height Cross Sections (RZA), and 2) 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. Special resolution is a 0.2 degree latitude/longitude grid for the balanced winds, and 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). The archived product is distributed in the netCDF-4 file format with metadata attributes included. Please expand "Details - Metadata, Documentation" section below for more details. Individual product (Datatype) description, documentation, and possible bulk access options are available under the "Product Details" link.
