[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...
Keywords: Snow water equivalent Arctic First-year sea ice Passive microwaves Surface based radiometer AMSR-E Ice roughness Climate change A SWE retrieval algorithm developed in-situ using passive microwave surface based radiometer data is applied to the Advanced Microwave Scanning Radiometer for Earth Observation System (AMSR-E). Snow water equivalent is predicted from two pixels located in Can...

Seasonal snow cover is a key component of the Earth’s energy balance and a key storage mechanism for water. In many areas of the world, people rely on snowmelt runoff for their water resources. For example, melting snow contributes upwards of 70% of the total annual water supply in the western U.S., and in India, Pakistan, Afghanistan, and Nepal snow and ice melt from the Hindu Kush and Himalay...
An algorithm for the estimate of the soil moisture content on a global scale from dual-frequency (Cand Xbands) microwave data of the Advanced Microwave Scanning Radiometer (AMSR-E) is presented in this paper. The algorithm is based on the brightness temperature at C-band and uses the Polarization Index at X-band to correct for vegetation effects. The retrieval is obtained by inverting a simplif...
