GSMaP_NRT (Global Satellite Mapping of Precipitation Near Real Time product)
The GSMaP_NRT is a near real time product for GSMaP (Global Satellite Mapping of Precipitation) algorithm. Algorithms for GSMaP_NRT are based on GSMaP_MVK (see algorithm description) but only using forward propagation of microwave estimated rainfall by cloud moving vector, to deliver products in near real time within four hours after observation. Microwave radiometers, such as TRMM/TMI, Aqua/AMSR-E, and DMSP/SSMI (F13, 14, 15), are used for retrieval of rainfall estimates. Although rainfall retrievals from microwave sounders, such as AMSU or MHS, are not included in current version, we're plannig to use those in a next version.
