Abstract:
The Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) observed the Earth in five frequencies at 6.6, 10.7, 18, 21, and 37 GHz in both horizontal and vertical polarization. Each frequency has a bandwidth of 250 MHz. The instrument was turned off on August 21, 1987 temporarily and was permanently turned off on July 6, 1988. The SMMR instrument provided long-term microwave data on sea-surface temperatures, rain rates over the ocenas, land brightness temperatures, wind speed at the ocean surface, sea ice, and atmospheric water vapor content. The SMMR Calibrated Temperature Tape (TCT) data products at NSIDC consist of . TCT radiances at footprint spatial resolution (78-098A-08W) . TCT brightness temperatures on 1/2 x 1/2 degree grids (78-098A-08Y) . TCT brightness temperatures on 0.25 x 0.25 degree grids (78-098A-08Z) 78-098A-08W SMMR TCT Radiances ------------------------------ This calibrated radiometric data set was generated from the Antenna Temperature Tape (TAT; original NSSDC ID 78-098A-08A) and was produced by an IBM 3081 computer onto 9-track, 6250-bpi, binary magnetic tapes. Each tape contains 3 days of brightness temperatures in the TAT resolution. There are also data on the incidence and reflected sun-boresight angles, and geographic and quality flags. The radiances contained in this data set were calibrated based on a model computation; consequently, they differ from those of the CELL-ALL data (original NSSDC ID 78-098A-08B), which were derived from prelaunch test data. Conversions from the CELL to the TCT radiances are possible by means of a linear equation. 78-098A-08Y SMMR TCT Half-Degree Brightness Temperatures -------------------------------------------------------- This set of calibrated global brightness temperature maps was produced by an IBM 3081 computer onto 9-track, 6250-bpi, binary magnetic tapes. It was generated from the Calibrated Temperature Tape (TCT; original NSSDC ID 78-098A-08W), and each map covers a 6-day period, i.e., 3 days of data. Daytime and nighttime calibrated horizontal and vertical polarization brightness temperatures from 5 bands (37, 21, 18, 10, and 6.6 GHz) are mapped onto grids of 1/2-deg latitude by 1/2-deg longitude (55 x 55 km at the equator). The maps range from 85 deg N. to 85 deg S. and from 180 deg W. to 180 deg E. There is approximately one tape per month. 78-098A-08Z SMMR TCT Quarter-Degree Brightness Temperatures ----------------------------------------------------------- This set of calibrated global brightness temperature maps was produced by an IBM 3081 computer onto 9-track, 6250-bpi, binary magnetic tapes. It was generated from the Calibrated Temperature Tape (TCT; original NSSDC ID 78-098A-08W), and each map covers a 6-day period, i.e., 3 days of data. Daytime and nighttime calibrated horizontal and vertical polarization brightness temperatures from 5 bands measured at 37 GHz are mapped onto grids of 1/4-deg latitude by 1/4-deg longitude (27.5 x 27.5 km). The maps range from 85 deg N. to 85 deg S. and from 180 deg W. to 180 deg E. There is approximately one tape per 3 mo.
