LIS Data Assimilation Examples NASA/GMAO-developed capabilities for sequential data assimilation have been implemented in the NASA/HSB Land Information System (LIS) framework. LIS is a comprehensive system that integrates the use of various land surface models, assimilation algorithms, observational sources for users at NASA, AFWA, NOAA, USDA and other agency investigators.

Soil moisture assimilation Assimilation product agrees better with ground data than satellite or model alone. Modest increase may be close to maximum possible with imperfect in situ data. Use data assimilation for generation of SMAP “Level 4” product. Skill (anomaly time series correlation coeff. with in situ data with 95% confidence interval) N SatelliteModelAssim.

(2007) J Geophys Res, doi:10.1029/2006JD008033.
Soil-Moisture-Active-Passive (SMAP) mission design Results Assimilation of (even poor) soil moisture retrievals adds skill (relative to model product). Published AMSR-E and SMMR assimilation products consistent with expected skill levels. Skill (R) of retrievals (surface soil moisture) Skill improvement of assimilation over model (ΔR) (root zone soil moisture) AMSR-E (Δ): ΔR=0.06 SMMR (□): ΔR=0.03 Q: How uncertain can retrievals be and still add useful information in the assimilation system? A: Synthetic data assimilation experiments. Skill measured in terms of R (=anomaly time series correlation coefficient against synthetic truth). Each plus sign indicates result of one 19-year assimilation integration over Red-Arkansas domain. Skill (R) of model (root zone soil moisture) Reichle et al. (2008) Geophys Res Lett, doi:10.1029/2007GL031986.
Normalized ROOT ZONE soil moisture improvement from assimilation of surface soil moisture Catchment or MOSAIC “truth” easier to estimate than Noah or CLM “truth”. Catchment and Mosaic work better for assimilation than Noah or CLM. Stronger coupling between surface and root zone provides more “efficient” assimilation of surface observations. How does land model formulation impact assimilation estimates of root zone soil moisture? Kumar et al. (2008) J. Hydromet., submitted. Multi-model soil moisture assimilation
Assimilation disaggregates GRACE data into snow, soil moisture, and groundwater. Assimilation estimates of groundwater better than model estimates.
