The Canadian Land Data Assimilation System (CaLDAS): Description and Synthetic Evaluation Study

A microwave land data assimilation system: Scheme and preliminary evaluation over China

[1] To make use of satellite microwave observations for estimating soil moisture, a dual‐pass land data assimilation system (DLDAS) is developed in this paper by incorporating a dual‐pass assimilation framework into the Community Land Model version 3 (CLM3). In the DLDAS, the model state (volumetric soil moisture content) and model parameters are jointly optimized using the gridded Advanced Mic...

An Earth Observation Land Data Assimilation System ( EO - LDAS )

20 Current methods for estimating vegetation parameters are generally sub-optimal in the way they 21 exploit information and do not generally track uncertainties. We look forward in the future to 22 operational data assimilation schemes to track land surface processes and exploit multiple types of 23 observation. Data assimilation schemes seek to combine observations and models in a statistical...

Land Surface Observation, Modeling and Data Assimilation

In what case do you like reading so much? What about the type of the land surface observation modeling and data assimilation book? The needs to read? Well, everybody has their own reason why should read some books. Mostly, it will relate to their necessity to get knowledge from the book and want to read just to get entertainment. Novels, story book, and other entertaining books become so popula...

Evaluation and assimilation of ATMS data in the ECMWF system

Assimilation of microwave brightness temperature in a land data assimilation system with multiobservation operators

[1] A radiative transfer model (RTM) that provides a link between model states and satellite observations (e.g., brightness temperature) can act as an observation operator in land data assimilation to directly assimilate brightness temperatures. In this study, a microwave Land Data Assimilation System (LDAS) was developed with three RTMs (The radiative transfer model for bare field (QH), land e...
