Next Challenge : Adding Integrated Value to the Measurements
- 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!!!
Towards an optimized management information product

Precipitation measurement missionGPM
Core satellite launched in February 2014
Really a constellation of many satellites
Like TRMM but at all latitudes
Measures light, heavy, frozen
Global coverage
2-4 hour frequency
~5-km resolution
Soil Moisture Active-PassiveSMAP
Launched January 2015
Beta product due October 2015
Soil moisture and freeze-thaw state
Global coverage
3-km radar and 9-km combined active-passive
2-3 day latency for level-3
Gravity Recovery and Climate ExperimentGRACE and GRACE-FO
Launched 2002
Still flying and returning data, with periodic outages to conserve power
Monthly, global TWSA
Measures total integrated water storage change beneath the satellites
~2-3 degree resolution

Regional Hydrologic Extremes Assessment System (RHEAS)
Built by Kostas Andreadis at JPL
Variable Infiltration Capacity (VIC) hydrology model
Ensemble Kalman Filter
Has been successfully applied and validated in the CONUS
Due to data latency: we will conduct provisional (~7-days) and stable (~3 months) hindcasts
Like a reanalysis for land surface hydrology

Western States Water Mission
The Western States Water Mission (WSWM) Will provide key stakeholders in California and the Western U.S. with actionable
information beginning in 2017
Planning for 2 data products : RHEAS VIC near-real-time preliminary product [~1-week latency] RHEAS VIC 3km2 catchment stable product [1979 to ~3-months ago]
Project personnel: James Famiglietti (Project Scientist), Ralph Basilio (Project Manager), Amy Trangsrud (Systems Engineer), Kostas Andreadis, Cedric David, JT Reager, Paul Ramirez, Dan Crichton, Duane Waliser, Michael Gunson,
Provides a tremendous opportunity for cooperation, synergy, and collaboration with CUAHSI:
Leveraging years of CUAHSI experience in water data sharing Specifically CUAHSI HIS for data downloading (e.g. USGS streamgages) WaterML to serve our results (catchment IDs, web mapping?) Links to Hydroshare, Hydrodesktop?
Questions, suggestions, discussion?
