Project Details:

The geography and dynamics of water across this pan-Arctic region are important elements of the larger Earth System especially given growing evidence of the vulnerability of the Arctic climate and terrestrial biosphere to global change. The scope of this multidisciplinary project is develop online, near-real time capabilities for rapid assessment and monitoring pan- Arctic water budgets and river discharge to the Arctic Ocean. Major goals of the project are: 1) to develop and implement Arctic-RIMS (Rapid Integrated Monitoring System) for acquiring near-real time data and producing "quick-look" outputs that characterize terrestrial water budgets across the pan-Arctic drainage region; 2) To create hydrologically-based re-analysis products using Arctic-RIMS and to analyze these time series in our continuing work on spatial and temporal variability of the pan-Arctic land mass. Arctic-RIMS integrates a variety of surface station network, remote sensing, and modeling data sets and tools developed by the co-Investigators to produce time-varying, region-wide land surface water budgets including river inputs to the Arctic Ocean.
