Estimation of Rainfall and its Error Characteristics from Satellite Observations
نویسندگان
چکیده
Currently, rainfall retrieval over ocean from passive microwave satellite observations represents the best compromise between estimation accuracy and spatial data coverage. Infrared data is available with higher temporal frequency from geostationary satellites but the link of top-of-the-atmosphere infrared emission to near-surface rainfall is very indirect. Therefore, all algorithms have to exploit the space-time relation between cloud cover / cloud top height and areal mean rainfall. With TRMM the first spaceborne precipitation radar became available and provides the most detailed information on precipitation vertical structure and quantity over both land and ocean up to date.

The accurate estimation of gridded daily precipitation is critical to hydrological modelling and water resource assessment. High resolution precipitation datasets based on gauge rainfall are the primary input to spatially distributed rainfall-runoff models and water balance calculations (e.g. Chiew et al., 2008). The spatial heterogeneity of rainfall variability is currently not captured adequa...

[1] The aim of this paper is to foster the development of an end-to-end uncertainty analysis framework that can quantify satellite-based precipitation estimation error characteristics and to assess the influence of the error propagation into hydrological simulation. First, the error associated with the satellite-based precipitation estimates is assumed as a nonlinear function of rainfall space-...
