Data Description

    Multi-Platform Cyclone Surface Wind Anaysis (MTCSWA) - The Multiplatform Tropical Cyclone Surface Wind Analysis (MTCSWA) algorithm combines data from multiple LEO and GEO satellites to create a mid-level (near 700 hPa) wind analysis product for estimating tropical cyclone surface winds. MTCSWA is used by weather forecasters (along with modeling data) to predict the expected wind speeds and storm surge for land-falling tropical cyclones and by emergency managers for disaster planning. The original version of the MTCSWA product became operational in November 2011 and is supplied to NOAA's National Hurricane Center (NHC) and the DOD Joint Typhoon Warning Center (JTWC), but was not archived in CLASS. The upgraded version of the MTCSWA product became operational on January 26, 2022. However, the CLASS archive began ingesting the data on September 7, 2022. The upgraded version includes the following data inputs: sounder data from SNPP, NOAA-18, NOAA-19, NOAA-20, Metop-B and Metop-C; imagery data from GOES-17, GOES-18, Himawari-8 and Meteosat-11. Storms are tracked in six tropical cyclone basins, with a 900 km domain centered on each active tropical cyclone. The number of products produced per year depends on the number of tracked storms and their duration. Storm identifiers include the location of the basin where the storm first forms. If a storm travels into a different basin it maintains the original identifier. Data files are generated every three hours during a storm event at a spatial resolution of 4.5 km by 10 degree azimuth. The MTCSWA 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 the "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.
