RSS > Remote Sensing Systems author NOAA CDR Program NOAA National Centers for Environmental Information collaborator NOAA CDR Program NOAA National Centers for Environmental Information author imageDigital This dataset from Remote Sensing Systems (RSS) consists of satellite swath-level brightness temperatures from the Special Sensor Microwave Imager/Sounder (SSMIS). SSMIS measures the natural microwave emission coming from the Earth’s surface in the spectral band from 19 to 85 GHz. There are roughly 15 orbits per day per satillite with a swath width of approximately 1400 km resulting in nearly global daily coverage. SSMIS onboard the DMSP F18 satellite is the first instrument that has been calibrated to the RSS Version 8 standard. The data record covers the time period from March 2010 through the present with a one month latency. Additional DMSP satellites for RSS Version 8 will follow as they are calibrated. This Version 8 is an update to Version 7 of the same product, also archived at NOAA/NCEI. Version 8 has improved calibration for land and ice scenes. The data file format is netCDF-4 with added metadata that follow the Climate and Forecast (CF) Conventions and Attribute Convention for Dataset Discovery (ACDD). This dataset provides advanced scientific researchers a high quality Climate Data Record (CDR) of Special Sensor Microwave/Imager (SSM/I) and Special Sensor Microwave Imager/Sounder (SSMIS) Brightness Temperatures. The Remote Sensing Systems (RSS) SSMI and SSMIS brightness temperatures deliver measurements of the radiance at the top of the atmosphere at a number of microwave frequencies. A number of factors determine the radiance in the atmosphere and land or ocean surface, making it difficult to directly evaluate the brightness temperature data. Instead, the brightness temperatures represent a fundamental climate data record (FCDR) that can be used by retrieval algorithms to determine a number of geophysical parameters such a surface wind speed, total column water vapor, rain rate, and sea ice extent.
