High Resolution GSMaP with Himawari 8

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
Global Satellite Mapping of Precipitation (GSMaP) is a system to produce global surface precipitation field with 0.1 degree and 1 hour resolution from geostationary infrared imager and microwave radiometer in low earth orbit (Ushio et al. 2019, Mega et al. 2018).

Improvement of the GSMaP Precipitation Retrieval Algorithm for Microwave Sounders Over Coast

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
We have improved a rainfall retrieval algorithm over coast for the Advanced Microwave Sounding Unit (AMSU) in order to upgrade to the Global Satellite Mapping of Precipitation (GSMaP) product version 8. As for the algorithm of product version 7, the zonal-mean monthly precipitation tends to overestimate low latitude coastal areas and to be a missing ...

Evaluation of GSMaP Rainfall Data in the Aceh Region

Journal of Climate Change Society
Rainfall measurement data in the field is quite limited, however, satellite data obtained by remote sensing methods are widely available. However, its accuracy must still be tested using observational rainfall data. The objective of this research was to validate GSMaP satellite estimated rainfall data with Automatic Rain Gauge (ARG) rainfall data at ...
