These atmospheric properties are calculated based on brightness temperature data from the Special Sensor Microwave/Imager (SSM/I) and the Special Sensor Microwave/Imager Sounder (SSMIS) on the Defense Meteorological Satellite Program (DMSP) spacecraft, using a neural network. ### Bands **Bands** Pixel size: 27830 meters (all bands) | Name | Units | Min | Max | Pixel Size | Description | |---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| | `air_temperature` | °C | -42.16\* | 42.77\* | 27830 meters | Air temperature at 10m | | `specific_humidity` | g/kg | 0.07\* | 37.06\* | 27830 meters | Specific humidity at 10m | | `wind_speed` | m/s | 0.13\* | 71.45\* | 27830 meters | Wind speed at 10m | | `fill_missing_qc` | | | | 27830 meters | Quality control flags | | Bitmask for fill_missing_qc - Bits 0-2: Quality control flags - 0: Pixel values from neural network - 1: Unused flag - 2: Snow/ice - 3: Over land - 4: Over lake - 5: Failed interpolation |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| \* estimated min or max value ### Terms of Use **Terms of Use** The NOAA CDR Program's official distribution point for CDRs is NOAA's National Climatic Data Center which provides sustained, open access and active data management of the CDR packages and related information in keeping with the United States' open data policies and practices as described in the President's Memorandum on "Open Data Policy" and pursuant to the Executive Order of May 9, 2013, "Making Open and Machine Readable the New Default for Government Information". In line with these policies, the CDR data sets are nonproprietary, publicly available, and no restrictions are placed upon their use.
