NOAA Geostationary Operational Environmental Satellite (GOES) I-M and N-P Series Block 11 Data

GOES Satellite Data - Block 11 (GVAR_B11) - GVAR is the data transmission format used to broadcast environmental data measured by the independent GOES Imager and Sounder instruments. The Block 11 data files contain ancillary instrument data and metadata that may be useful to expert users. All sounder data will be included in Block 11, but not all Block 11's will contain sounder data. As the GVAR data are received by NOAA, the sounder blocks are stripped out and converted into McIDAS AREA format for final archive.

PurposeThe Sounder performs a spacelook calibration sequence at a fixed nominal rate every 2 minutes. During a Sounder spacelook calibration, 40 raw Sounder data blocks are acquired at the spacelook coordinates. Unlike the Imager, the Sounder has no defined preclamp or clamp activity. A data analyses is also performed for the Sounder spacelook data. The resulting statistics are packaged in the Sounder Block 11. The Sounder performs a Blackbody sequence every 20 minutes. During the sequence, the scanning mirror is rotated in the N-S direction through an angle of approximately 180 degrees to present a view of the Blackbody surface to the imaging detectors. Like the Imager, the Blackbody surface temperature is maintained at a nominal 290˚ K..
Use Limitations
  • GOES-15 was decommissioned on March 2, 2020, being replaced by GOES-17 as the operational GOES-West satellite. Please go to the GRABIPRD search page to search and order recent GOES terrestrial data and products. Most of the level 2 products are available, as well.
