Using Satellite Error Modeling to Improve GPM-Level 3 Rainfall Estimates over the Central Amazon Region
This study aims to assess the characteristics and uncertainty of Integrated Multisatellite Retrievals for Global Precipitation Measurement (GPM) (IMERG) Level 3 rainfall estimates and to improve those estimates using an error model over the central Amazon region. The S-band Amazon Protection National System (SIPAM) radar is used as reference and the Precipitation Uncertainties for Satellite Hyd...
متن کاملUncertainty 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 کاملEvaluation of Satellite Rainfall Estimates over the Chinese Mainland
Benefiting from the high spatiotemporal resolution and near-global coverage, satellite-based precipitation products are applied in many research fields. However, the applications of these products may be limited due to lack of information on the uncertainties. To facilitate applications of these products, it is crucial to quantify and document their error characteristics. In this study, four sa...
متن کاملComparing rainfall estimates derived from rain gages and satellite images at the eastern Mediterranean region
This article aims to test a satellite infrared (IR) technique for estimating rainfall over Mediterranean. On that purpose, we use 6hr, 12hr and 24hr cumulative rainfall measurements, obtained from a large set of gages located at the eastern Mediterranean region, during October 2004. Two kinds of comparisons are undertaken. First, rainfall estimates derived from satellite images are projected to...
متن کاملInvestigation of Discrepancies in Satellite Rainfall Estimates over Ethiopia
Tropical Applications of Meteorology Using Satellite and Ground-Based Observations (TAMSAT) rainfall estimates are used extensively across Africa for operational rainfall monitoring and food security applications; thus, regional evaluations ofTAMSATare essential to ensure its reliability. This study assesses the performance of TAMSAT rainfall estimates, along with the African Rainfall Climatolo...
