Abstract:
Character string:
The PRE-GVAR data family provides reprocessed GOES Level-1 data from the Visible and Infrared Spin Scan Radiometer (VISSR) and from the VISSR Atmospheric Sounder (VAS). VISSR was active on GOES 1-3 and SMS 1-2, while VAS was active on GOES 4-7. These legacy instruments provided cloud imagery and atmospheric temperature and humidity soundings, which were used to monitor the atmosphere for severe weather; such as tornadoes, flash floods, hail storms, and hurricanes. GOES satellites are positioned 36,000 km (22,000 statute miles) above the equator. This fixed position above the earth allowed the satellites to scan large geographic regions of the Western Hemisphere. Coverage is provided by two GOES spacecraft, one at -75.0 Longitude (GOES East) and the other at -135.0 Longitude (GOES West). GOES VISSR and VAS reprocessed products were produced by the University of Wisconsin Space Science Engineering Center (SSEC) and archived by The NOAA National Centers for Environmental Information (NCEI). The archived products are distributed via CLASS in raw data and McIDAS file formats. Expand the "Details - Metadata, Documentation" section below for more information. Note: In 2022 an effort was taken to reprocess the SMS 1-2 and GOES 1-7 data to address ingest errors during the original read and processing from U-matic tape in the early 2000s. In addition to the ingest errors of the original data, there also existed multiple versions of the same image when a U-matic tape was read multiple times. During the reprocessing multiple occurrences of the same images were merged into a single best image. The following changes described did not make changes to the data from what would have been originally broadcast, but rather, it corrected errors due to ingest problems of the original data.
