Assessing satellite-based precipitation estimates in the Southern Appalachian mountains using rain gauges and TRMM PR
A study was performed using the first full year of rain gauge records from a newly deployed network in the Southern Appalachian mountains. This is a region characterized by complex topography with orographic rainfall enhancement up to 300% over small distances (<8 km). Rain gauge observations were used to assess precipitation estimates from the Precipitation Radar (PR) on board of the TRMM sate...
متن کاملWalnut Improvement Program ( Usda - Ars
The primary goal of the Walnut Improvement Program, which was initiated in 1982 as a cooperative effort between USDA-ARS and U.C. Davis, is to develop germplasm with increased resistance or tolerance to the two major diseases limiting commercial production of Persian walnuts. These are the blackline and the Phytophthora root and crown rot diseases. Also under the auspices of this program are th...
متن کاملImproving Rainfall Erosivity Estimates Using Merged TRMM and Gauge Data
Soil erosion is a global issue that threatens food security and causes environmental degradation. Management of water erosion requires accurate estimates of the spatial and temporal variations in the erosive power of rainfall (erosivity). Rainfall erosivity can be estimated from rain gauge stations and satellites. However, the time series rainfall data that has a high temporal resolution are of...
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 کاملSatellite-based Flood Modeling Using TRMM-based Rainfall Products
Increasingly available and a virtually uninterrupted supply of satellite-estimatedrainfall data is gradually becoming a cost-effective source of input for flood predictionunder a variety of circumstances. However, most real-time and quasi-global satelliterainfall products are currently available at spatial scales ranging from 0.25o to 0.50o andhence, are considered somewhat coarse for dynamic h...
