Statistical and Dynamical Mesoscale Climate Downscaling

“Climate downscaling" is a practice whereby coarse-resolution climate data -- which comes from global atmospheric reanalyses (e.g., the "NCEP/NCAR Reanalysis") or global climate models (GCMs) -- is fed to physically-based or empirically-based techniques to simulate regional- or local-scale climate at much finer spatial and temporal resolution. The need for climate downscaling has grown tremendously in the past decade, as the scientific community endeavors to address an increasing number of weather and climate impacts issues related to agriculture, water resources, human health, etc.
