    Abstract

    The historical atmospheric data (precipitation, air temperature and solar radiation) were reconstructed at hourly interval with 3-km resolution from NCAR/NCEP Reanalysis data by dynamical downscaling (MM5) over Northern California and the performance for reconstructed data were validated by ground observations and by spatial data from PRISM. The validation results yielded very satisfactory results in the case of MM5 simulations from the downscaling of NCAR/NCEP reanalysis data. From this study, it is found that the reconstructed atmospheric data by MM5 atmospheric model can provide the necessary data for hydrologic or environmental models to be used in the watersheds with limited or insufficient ground observations. Furthermore, the results of this study imply that dynamical downscaling of the Global Climate Model (GCM) future climate projections for the simulation of future conditions by means of the MM5 atmospheric model can be a useful tool for the future climate change assessment.
