Moving toward optimum use of gridded precipitation forcings in hydrologic modeling
A discussion of these issues was initiated at the 2010 AMS annual meeting. Approaches to constructing precipitation, temperature, and radiation balance Analyses of Record are under discussion among several NWS offices. Finally, tests of different approaches to precipitation and temperature reanalysis have been undertaken at some NWS River Forecast Centers, and the impacts on calibration of hydrologic models has been evaluated. This presentation will feature a summary of the many methods that have been applied to retrospective and real-time precipitation analysis, including recent advances in radar precipitation estimation, and the suitability of the approaches to hydrologic applications. We expect to stimulate further discussion on how the final goal of a multi-decade gridded precipitation dataset might be achieved, given the wide variety of options for input observations and estimates and analysis techniques.
