A Regional, Integrated Monitoring System for the Hydrology of the Pan-Arctic Land Mass

摘要: Work under this NASA contract developed a system for monitoring and historical analysis of the major components pan-Arctic terrestrial water cycle. It is known as Arctic-RIMS (Regional Integrated Hydrological Monitoring System Pan-Arctic Landmass). The uses products from EOS-era satellites, numerical weather prediction models, station records other data sets in conjunction with an atmosphere-land surface budgeting scheme. intent was to compile operational (at 1-2 month time lags) gridded fields precipitation (P), evapotranspiration (ET), P-ET, soil moisture, freeze/thaw state, active layer thickness, snow extent its equivalent, storage, runoff simulated discharge along estimates non-closure budget. Using "baseline" schemes atmospheric reanalyses pre-EOS satellite data, budget were compiled provide series. goals outlined original proposal can be summarized follows: 1) Use EOS hydrologic regions including snowcover/snow equivalent (SSM/A MODIS, AMSR) near-surface dynamics (Sea Winds on QuikSCAT ADEOS I4 SSMI AMSR). 2) Implement use streams, allied models produce outputs that fully characterize aerological budgets. 3) Compile hydrologically-based providing long-term baseline spatial temporal variability
