Assessment of Level-3 Gridded Global Precipitation Mission (GPM) Products Over Oceans

Assessment of GPM and TRMM Precipitation Products over Singapore

The evaluation of satellite precipitation products (SPPs) at regional and local scales is essential in improving satellite-based algorithms and sensors, as well as in providing valuable guidance when choosing alternative precipitation data for the local community. The Tropical Rainfall Measuring Mission (TRMM) has made significant contributions to the development of various SPPs since its launc...

Global Precipitation Mission (GPM) and Dual-Wavelength Radar (DPR)

Global precipitation measurement is essential not only for the research of the global change but also for the water resources management. Currently, satellite precipitation measurement is not sufficient for the detailed study of the precipitation and is far from enough for the water resources management which requires very high spatial and temporal resolution. To fill the gap at least partly, t...

Evaluation of monthly gridded precipitation data products ERA-Interim, PERSIANN-CDR, PERSIANN-CCS and CRU over Khuzestan province

Deficiency and inappropriate distribution of reengage station is one of challenges faced by researchers in hydrology and climate science. In this research, evaluate the applicability of four gridded precipitation data products ERA-Interim, PERSIANN-CDR, PERSIANN-CCS and CRU as a supplement or substitute for ground data in a monthly time scales. This assessment was done by comparison with observ...

Optical alignment of the Global Precipitation Measurement (GPM) star trackers

The optical alignment of the star trackers on the Global Precipitation Measurement (GPM) core spacecraft at NAS A Goddard Space Flight Center (GSFC) was challenging due to the layout and structural design of the GPM Lower B us Structure (LBS) in which the star trackers are mounted as well as the presence of the star tracker shades that blocke d line-of-sight to the primary star tracker optical ...
