GSMaP is a dataset of hourly global rainfall maps, a re-analysis version of the Near-Real-Time product by JAXA Global Rainfall Watch for meteorological and climate studies. Different products are part of GSMaP we copied the Gauge-calibrated Reanalysis product GSMaP_Gauge_RNL v6. Variable is rainfall rate and gauge-calibrated rain rate in mm/h, original units of raw product are mm/hr we converted to standard units kg m^-2 s^-1 in the netcdf version. The global grid is limited to 60N-60S and resolution is 0.1 degree latitude/longitude. Temporal resolution is up to 1 hour (averaged from 00 minutes to 59 minutes). The current algorithm version is 6, version 7 is being released. Product version is v03 which doesn't detect snowfall, although a new version v04 which fixes the issue and use v7 of the algorithm is in preparation. More information on the upgrade and changes to the product are available [http://www.eorc.jaxa.jp/GPM/doc/product_info/release_note_gsmapv04-v7_en.pdf | here]. The Gauge_RNL product is updated only occasionally currently covers from March 200 to February 2014. We downloaded the daily data (average between 00 to 23 hours) but 1 hourly is available too.

Global Satellite Mapping of Precipitation from JAXA

GSMaP is a dataset of hourly global rainfall maps, a re-analysis version of the Near-Real-Time product by JAXA Global Rainfall Watch for meteorological and climate studies. Different products are part of GSMaP we copied the Gauge-calibrated Reanalysis product GSMaP_Gauge_RNL v6. Variable is rainfall rate and gauge-calibrated rain rate in mm/h, original units of raw product are mm/hr we converted to standard units kg m^-2 s^-1 in the netcdf version. The global grid is limited to 60N-60S and resolution is 0.1 degree latitude/longitude. Temporal resolution is up to 1 hour (averaged from 00 minutes to 59 minutes). The current algorithm version is 7, version 6 is also available. The product version for v6 is v03 which doesn't detect snowfall, the new version v04, used for v7, fixes the issue. More information on the upgrade and changes to the product are available here. The Gauge_RNL product is updated only occasionally currently v7 covers from March 2014 to december 2019, while v6 covers from March 2000 to February 2014. We downloaded the daily data (average between 00 to 23 hours) but 1 hourly is available too. More information is available from the PDF and readme file available in the directory and online and from the GSMaP webpage
