National Climate Assessment - 2011 NASA Centers Call For Proposals
Lead PI and Center: Michael Jasinski, Goddard Space Flight Center
Title: An Integrated Terrestrial Water Analysis System for the NCA
Proposal Type: Enabling Tools
Project Website: http://ldas.gsfc.nasa.gov/NCA-LDAS/
Background:
This proposal leverages NASA Earth Sciences Division and other agency investments in several recent projects at GSFC. These projects have separately demonstrated the value of assimilating AMSR-E based soil moisture; GRACE-based terrestrial water storage (TWS); MODIS-based estimates of irrigation intensity; MODIS-based estimates of Snow Covered Area (SCA); and AMSR-E-based estimates of Snow Water Equivalent (SWE).
Proposed Effort:
In this project, we will consolidate all of the above capabilities in LIS and provide a multi-model terrestrial water analysis from 1979- present based on the North American Land Data Assimilation System atmospheric inputs.
The objectives of this proposal are
The proposed work will consist of the following four sub-tasks:
Results/Significance:
The hypothesis to be tested in this proposal is that assimilating NASA’s satellite soil moisture, SWE, SCA, TWS and irrigation products into an NCA-LDAS will produce improved characterization of the continental scale water budget, which will directly improve the monitoring and prediction of climate-relevant water availability indicators, including droughts and floods. Specific science questions to be addressed include:
- Snowpack-streamflow-flood anomalies?
- Groundwater-soil moisture-evapotranspiration-drought anomalies?
- Irrigation impacts?
