Description
Summary:As one of Japanese Global Precipitation Measurement (GPM) products, Global Satellite Mapping of Precipitation (GSMaP) product has been provided by Japan Aerospace Exploration Agency (JAXA) to distribute hourly global precipitation map with 0.1×0.1 deg. lat/lon grid. The GSMaP products are composed of "standard product", "near-real-time product", "real-time product", and "reanalysis product". The standard products are processed 3 days after observation, and the near-real-time products are processed 4 hours after observation. In addition, the real-time version, GSMaP_NOW has been provided by the JAXA over the geostationary satellite "Himawari-8" region since Nov. 2015. Recently, the GSMaP algorithms were majorly updated on September 2014 and January 2017. The current paper describes overviews of the GSMaP products and recent progress of the GSMaP product.
