Product Summary
GSMaP Hourly dataset is obtained from the Dual-frequency Precipitation Radar (DPR) sensor onboard Global Precipitation Measurement (GPM), other GPM constellation satellites, and Geostationary satellites produced by the Japan Aerospace Exploration Agency (JAXA).
The GSMaP is generated based on a multi-satellite algorithm under the GPM mission, and the accuracy has been improved by DPR data and information. It offers a map of global precipitation by combining: estimated precipitation based on multiple microwave radiometers (imager/sounder) and cloud moving information obtained from geostationary infrared (IR) data.
The GSMaP algorithm can be roughly divided into the following three algorithms: microwave imager (MWI) algorithm, microwave sounder (MWS) algorithm, and microwave-Infrared (IR) combined (MVK) algorithm. A global satellite mapping of precipitation can be subject to standard processing or near real-time processing.
In standard processing, hourly observation data is processed then the data is averaged monthly. Near real-time processing provides a higher data frequency than standard processing (every hour). The provided formats are HDF5, text, GeoTIFF and NetCDF. The Sampling resolution is 0.1 degree grid. The projection method is EQR.
The statistical period is 1 hourly. The current version of the product is Version 5. The Version 4 is also available. The generation unit is global.
