1 Jet Propulsion Laboratory, California Institute of Technology The Western States Water Mission CUAHSI Hydroinformatics meeting 16 July 2015
2 Water Cycle and Freshwater Availability Next Challenge : Adding Integrated Value to the Measurements FRESHWATER STORAGE IN ICE AND SNOW Airborne Snow Observatory (ASO) CLOUDS CloudSat, MODIS WATER VAPOR AIRS, MLS, GPS-RO Tempest (2017) PRECIPITATION GPM RainCube (2017) RIVERS & LAKES SWOT (2020) EVAPOTRANSPIRATION ECOSTRESS (2017) WATER STORAGE IN OCEANS Jason Series, SWOT (2020) GROUND-WATER GRACE, GRACE-FO (2017) SOIL MOISTURE SMAP EVAPORATION Aquarius
3 Towards an optimized management information product - There is some best-estimate of water state based on a combination of models and data - Beyond scientists and to user friendly applications for water managers and the public - Active operational assimilation of all current products - Remove obstacles in downloading, aggregating and interpreting outputs - Advancing to the management spatial scale - Including robust uncertainties!!!
4 The Western States Water Mission: An example of a systems approach to hydrology Observations Coupled and Validated Models Stakeholders/Customers Estimates with Uncertainties (Prospective customers) Colorado Water Conservation Board CA Total Usable Freshwater (million acre-feet) month ago 1 season ago (Notional) 1 year ago Retrospective Record
5 The Western States Water Mission: A robust effort to improve state estimates of water availability ASO RHEAS State Estimation with Uncertainties Near-Real Time, plus 1979-present Western US 3km 2 catchment-grid with river routing Decision support for Western States A. Konstantinos/JPL Operational, high-resolution assimilation of satellite, airborne, in situ products R2O path for process modeling & optimal assimilation practices for GRACE, SMAP, ASO, SWOT, etc
