Rainfall-triggered flood and landslide hazards pose significant threats to human lives infrastructure worldwide. This study aims evaluate the applicability of three satellite rainfall data sets—namely, CMORPH, GPM, TRMM—for prediction using a coupled hydrological-slope stability model. The spatial distribution annual from sets was similar that gauge rainfall, with an increasing trend north sout...

Satellite precipitation products from the Global Precipitation Measurement (GPM) mission and its predecessor the Tropical Rainfall Measuring Mission (TRMM) are a critical data source for hydrological applications in ungauged basins. This study conducted an initial and early evaluation of the performance of the Integrated Multi-satellite Retrievals for GPM (IMERG) final run and the TRMM Multi-sa...

A method using a nonlinear auto-regressive neural network with exogenous input (NARXnn) to retrieve time series soil moisture (SM) that is spatially and temporally continuous and high quality over the Heihe River Basin (HRB) in China was investigated in this study. The input training data consisted of the X-band dual polarization brightness temperature (TB) and the Ka-band V polarization TB fro...

Reliable precipitation is crucial for hydrological studies over Tibetan Plateau (TP) basins with sparsely distributed rainfall gauges. In this study, four widely used products, including the Asian Precipitation Highly Resolved Observational Data Integration Towards Evaluation of water resources (APHRODITE), High Asia Reanalysis (HAR), and satellite-based estimates from Global Measurement (GPM) ...

Since the TRMM launch in 1997, global rain estimation by microwave radiometer has been improved referring the PR data. The microwave radiometer observation becomes the major observation tool for the Global Precipitation Measurement (GPM). However, there are still gaps of global rainfall distribution between PR and TMI (e.g. Berg et al., 2002). One of the major issues for rain retrieval algorith...

In final form 30 May 2007 © 2007 American Meteorological Society he global hydrological cycle is central to Earth’s climate system, with rainfall and the physics of precipitation formation acting as the key links in the cycle. Two-thirds of global rainfall occurs in the Tropics with the associated latent heat (LH) release accounting for three-fourths of the total heat energy available to Earth’...

In order to secure the quality of precipitation estimates, ground validation (GV) of satellite data and retrieval algorithms is essential. Since end-to-end comparisons between instantaneous precipitation data observed by satellite and groundbased instruments is not enough to improve the algorithms. The error of various physical parameters in the precipitation retrieval algorithms (e.g. attenuat...
