Huge amounts of evaporation and precipitation exist over the ocean and play an important role in the global climate system. Therefore, evaluation of freshwater flux is critical for understanding the mechanism of global climate change. Recently we can use three kinds of global freshwater flux products such as in situ data, satellite data and reanalysis data. Although various studies were carried...

The Tropical Rainfall Measuring Mission (TRMM) satellite carries two instruments to measure precipitation: the TRMM Microwave Imager (TMI) and the Precipitation Radar (PR). Examination of instantaneous orbit data from TMI and PR reveals several problems in the TRMM products that are not readily discernible from monthly or areal averaged data sets. TMI rainfall processing algorithms yield signif...

The validity of two reanalysis (ERA5 and MEERA2) seven satellite-based (CHIRPS, IMERG, PERSIANN-CCS, PERSIANN-CDR, PERSIANN-PDIR, PERSIANN, TRMM) precipitation products was assessed in relation to the observations situ weather stations installed different topographical climatic regions Pakistan. From 2010 2018, all were evaluated on daily, monthly, seasonal, annual bases at a point-to-pixel sca...

Abstract Satellite-based precipitation products and reanalysis have the potential to overcome lack of information in regions where there are no or insufficient rain gauges achieve any hydrological study. The Google Earth Engine (GEE) data analysis platform has its repository with global coverage that offers different geospatial capable measuring amount precipitation. However, it is necessary ev...
