Regional atmospheric model simulations over the Mackenzie, Kuparuk, and Lena watersheds have been completed for the time
period September 1998 through September 2000 using domains with 50 km and nested 10 km horizontal grid spacing. These
simulations are part of a 5-year collaborative project between the University of Colorado, Iowa State University, and the
University of Alaska AŸA›A›ƒ_sAªA›ƒ,ª" Fairbanks to model coupled atmosphere AŸA›A›ƒ_sAªA›ƒ,ª" land hydrologic processes
over watersheds with continuous and discontinuous permafrost. Output from the atmospheric model simulations will be used to
drive a very high resolution land hydrology model, and potential feedbacks between the atmosphere and land process will be
studied with a series of uncoupled model experiments. Initial results from the atmospheric model simulations will be
presented, with a focus on model validation of the near surface atmospheric state. Particular attention will be given to
model errors that are likely to have the largest impact in forcing the land hydrology model. A discussion of differences
between the 50 km and 10 km horizontal grid spacing results will also be included.
