Prototype of NASA's global precipitation measurement mission ground validation system
NASA is developing a Ground Validation System (GVS) as one of its contributions to the Global Precipitation Mission (GPM). The GPM GVS provides an independent means for evaluation, diagnosis, and ultimately improvement of GPM spaceborne measurements and precipitation products. NASA's GPM GVS consists of three elements: field campaignslphysical validation, direct network validation, and modeling...
متن کاملGlobal Satellite Mapping of Precipitation (gsmap) Project
Precipitation is one of the most important parameters on the earth system, and the global distribution of precipitation and its change are essential data for modeling the water cycle, maintaining the ecosystem environment, agricultural production, improvements of the weather forecast precision, flood warning and so on. In the GPM (Global Precipitation Measurement) project, the microwave radiome...
متن کاملارزیابی دادههای بارش زمینی، ماهواره GPM و MERRA (مطالعه موردی: حوضه آبریز کشف رود)
In recent decades, satellite and model- based precipitation products has attracted attention of the scientists and researchers in hydrology and other disciplines. The purpose of this research is quantitative comparison of MERRA and GPM satellite precipitation products with ground station precipitation values as reference data in Kashafrud basin. The important point about these data is their ...
متن کاملCharacterization of precipitation product errors across the United States using multiplicative triple collocation
Validation of precipitation estimates from various products is a challenging problem, since the true precipitation is unknown. However, with the increased availability of precipitation estimates from a wide range of instruments (satellite, ground-based radar, and gauge), it is now possible to apply the triple collocation (TC) technique to characterize the uncertainties in each of the products. ...
متن کاملUpper Blue Nile basin water budget from a multi-model perspective
Improved understanding of the water balance in the Blue Nile is of critical importance because of increasingly frequent hydroclimatic extremes under a changing climate. The intercomparison and evaluation of multiple land surface models (LSMs) associated with different meteorological forcing and precipitation datasets can offer a moderate range of water budget variable estimates. In this context...
