—Dense media radiative transfer (DMRT) theory is used to study the multiple-scattering effects in active microwave remote sensing. Simplified DMRT phase matrices are obtained in the 1–2 frame. The simplified expressions facilitate solutions of the DMRT equations and comparisons with other phase matrices. First-order, second-order, and full(More)
— Snow is a critical component of the global water cycle and climate system, and a major source of water supply in many parts of the world. There is a lack of spatially distributed information on the accumulation of snow on land surfaces, glaciers, lake ice and sea ice. Satellite missions for systematic and global snow observations will be essential to(More)
—Characteristics of the Ku-band polarimetric scat-terometer (POLSCAT) data acquired from five sets of aircraft flights in the winter months of 2006–2008 for the second Cold Land Processes Experiment (CLPX-II) in Colorado are described in this paper. The data showed the response of the Ku-band radar echoes to snowpack changes for various types of background(More)
Radar backscatter at Ku-and X-band frequencies is very sensitive to the physical properties of the snow pack. This sensitivity is explored by the satellite mission COld REgions Hydrology High-resolution Observatory (CoReH2O) which has been selected for scientific and technical feasibility studies within the Earth Explorer Programme of the European Space(More)
The satellite mission COld REgions Hydrology High-resolution Observatory (CoReH2O) is one of the six missions which has been selected for scientific and technical feasibility studies within the Earth Explorer Programme of the European Space Agency. The mission aims at closing major gaps in present snow and ice observations. The focus of the mission is on(More)
— Taking into account the needs for improved, spatially detailed observations of snow and ice in climate research, hydrology, and glaciology, the satellite mission COld REgions Hydrology High-resolution Observatory, CoRe-H 2 O, was proposed to ESA. As payload a co-and cross-polarized Ku-band (17.2 GHz) and X-band (9.6 GHz) SAR was selected, because of its(More)
The COld REgions Hydrology High-resolution Observatory (CoReH 2 O) satellite mission was selected for detailed scientific and technical studies within the Earth Explorer Programme of ESA. The sensor is a dual frequency SAR, operating at 17.2 GHz and 9.6 GHz, VV and VH polarizations The mission will deliver spatially distributed snow and ice observations to(More)
