GSMaP\nis a product of the Global Precipitation Measurement (GPM) mission,\nwhich provides global precipitation observations at three hour\nintervals. Values are estimated using multi-band passive microwave\nand infrared radiometers from the GPM Core Observatory satellite\nand with the assistance of a constellation of other satellites. GPM's\nprecipitation rate retrieval algorithm is based on a radiative\ntransfer model. The gauge-adjusted rate is calculated based on\nthe optimization of the 24h accumulation of GSMaP hourly rain rate\nto daily precipitation by NOAA/CPC gauge measurement. This dataset\nis processed by GSMaP algorithm version 6 (product version 3).\nSee [GSMaP Technical Documentation](https://www.eorc.jaxa.jp/GPM/doc/algorithm/GSMaPforGPM_20140902_E.pdf)\nfor more details.\n\nThe operational GSMaP dataset (from 2014 to present)\nis also \\[available\\](JAXA_GPM_L3_GSMaP_v6_operational\\].\n\n### Bands\n\n\n**Pixel Size**\n\n11132 meters\n\n**Bands**\n\n| Name | Units | Min | Max | Pixel Size | Description |\n|-----------------------|---------|----------|----------|------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|\n| `satelliteInfoFlag` | | | | meters | Satellite/sensor used |\n| Bitmask for satelliteInfoFlag - Bit 0: NOAA/CPC Globally Merged IR data - 0: No - 1: Yes - Bit 1: TRMM/TMI - 0: No - 1: Yes - Bit 2: GPM-Core/GMI - 0: No - 1: Yes - Bit 3: Megha-Tropiques/MADRAS - 0: No - 1: Yes - Bit 4: Megha-Tropiques/SAPHIR - 0: No - 1: Yes - Bit 5: ADEOS-II/AMSR - 0: No - 1: Yes - Bit 6: Aqua/AMSR-E - 0: No - 1: Yes - Bit 7: GCOM-W1/AMSR2 - 0: No - 1: Yes - Bit 8: GCOM-W2/AMSR2 - 0: No - 1: Yes - Bit 9: GCOM-W3/AMSR2 - 0: No - 1: Yes - Bit 10: DMSP-F11/SSM/I - 0: No - 1: Yes - Bit 11: DMSP-F13/SSM/I - 0: No - 1: Yes - Bit 12: DMSP-F14/SSM/I - 0: No - 1: Yes - Bit 13: DMSP-F15/SSM/I - 0: No - 1: Yes - Bit 14: DMSP-F16/SSM/I - 0: No - 1: Yes - Bit 15: DMSP-F17/SSM/I - 0: No - 1: Yes - Bit 16: DMSP-F18/SSM/I - 0: No - 1: Yes - Bit 17: DMSP-F19/SSM/I - 0: No - 1: Yes - Bit 18: DMSP-F20/SSM/I - 0: No - 1: Yes - Bit 19: NOAA-15/AMSU-A/B - 0: No - 1: Yes - Bit 20: NOAA-16/AMSU-A/B - 0: No - 1: Yes - Bit 21: NOAA-17/AMSU-A/B - 0: No - 1: Yes - Bit 22: NOAA-18/AMSU-A/B - 0: No - 1: Yes - Bit 23: NOAA-19/AMSU-A/B - 0: No - 1: Yes - Bit 24: NPP/ATMS - 0: No - 1: Yes - Bit 25: JPSS-1/ATMS - 0: No - 1: Yes - Bit 26: MetOp-A/AMSU-A/MHS - 0: No - 1: Yes - Bit 27: MetOp-B/AMSU-A/MHS - 0: No - 1: Yes - Bit 28: MetOp-C/AMSU-A/MHS - 0: No - 1: Yes ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||\n| `hourlyPrecipRate` | mm/hr | 0\\* | 200.31\\* | meters | Snapshot of hourly precipitation rate |\n| `hourlyPrecipRateGC` | mm/hr | 0\\* | 200\\* | meters | Snapshot of hourly precipitation rate adjusted to rain gauge |\n| `observationTimeFlag` | h | -72.52\\* | 14.97\\* | meters | Relative time from the starting time of the file to the time of microwave radiometer (imager/sounder) observing.
