Uncertainty Assessments of Satellite Derived Rainfall Products
Accurate and consistent rainfall observations are vital for climatological studies in support of better planning and decision making. However, estimation of accurate spatial rainfall is limited by sparse rain gauge distributions. Satellite rainfall products can thus potentially play a role in spatial rainfall estimation but their skill and uncertainties need to be under-stood across spatialtime...
متن کاملTRMM satellite rainfall data
Spatial rainfall is a key input to Distributed Hydrological Models, which is the most important limitation for the accuracy of hydrological models. Model performance and uncertainty could increase when rain gauge is sparse. Satellite-based precipitation products would be an alternative to ground-based rainfall estimates in present and 5 the foreseeable future, however, it is necessary to evalua...
متن کاملMerging Satellite Measurements of Rainfall Using Multi-scale Imagery Technique
Several passive microwave satellites orbit the Earth and measure rainfall. These measurements have the advantage of almost full global coverage when compared to surface rain gauges. However, these satellites have low temporal revisit and missing data over some regions. Image fusion is a useful technique to fill in the gaps of one image (one satellite measurement) using another one. The proposed...
متن کاملIntercomparison of Rainfall Estimates from Radar, Satellite, Gauge, and Combinations for a Season of Record Rainfall
Rainfall products from radar, satellite, rain gauges, and combinations have been evaluated for a season of record rainfall in a heavily instrumented study domain in Oklahoma. Algorithm performance is evaluated in terms of spatial scale, temporal scale, and rainfall intensity. Results from this study will help users of rainfall products to understand their errors. Moreover, it is intended that d...
متن کاملThird generation rainfall climatologies: satellite rainfall and topography provide a basis for smart interpolation
This short paper discusses a technique for producing ‘improved rainfall estimates’ (IRE) for Africa. The central objective of IRE is to make reasonable use of the high resolution mean fields, moderate density gauge data, and timely satellite rainfall data typically available at the national/regional level in Africa. In general, traditional rainfall interpolation schemes can be classified into t...
