Science utilization
Improve predictions (water cycle)
- Variables include: Soil moisture, snow water equivalent, surface runoff, evapotranspiration, rainfall
--Take data from Earth-Sun observations and plug into Earth systems models to make predictions and observations --
- Groundwater = GRACE
- Precipitation = TRMM/GPM
- TRMM will lead to GPM for Global precipitation
- Soil Moisture = Hydros (cancelled, hopefully be back in 07)
- We plan to address soil moisture intensively - Hyrdos provides soil moisture and freeze/thaw info
- Snow
- Surface water
- Snow-water equivalent measured by AMSR-E
--Sensors in concept CLPP mission
--Pathfinder proposed mission provides reservoir height and discharge estimates using 3 methods
- Altimetry
- Laser
- Parallax interferometer approach
--Land Information System (LIS) high performance, high resolution (1 km) for local to global land modeling and data assimilation system
- Follows ESMF modeling framework -- single or multiple processors
- 5+ land surface models -- ingest different types of data sets, dependent on availability, model the data, outputs include: soil moisture, ET, Water availability parameters.
- Goal is to get groups to use the suite more.
