Brightness Temperature and Sea Ice Concentration Data


Availability: Data Accessible Elsewhere

Time span: 1973-01-01 to 1976-12-31


This data set contains sea ice concentrations and brightness temperatures that were generated by an IBM computer onto 6250-bpi, EBCDIC magnetic tape. It is derived from measurements taken at 19-GHz frequency. Calibrated brightness temperatures, sea ice concentrations, and ancillary data such as surface air temperature and pressure are presented in a 293 x 293 polar stereographic grid that encloses the 50 deg S. latitude circle and 50 deg N. latitude circle, respectively. The cell size varies from 32 x 32 km at the pole to 28 x 28 km at 50 deg S. Monthly, multiyear monthly, and yearly data were created for 4 yr from 1973 to 1976, except for 7 mo for which there were insufficient data.

This data set is available from the National Snow and Ice Data Center, (NSIDC) which is also one of the EOSDIS DAACs. All documentation has been transferred from NSSDC to NSIDC.
