TL;DR: Under vegetated conditions for which soil moisture estimates may not be feasible using current radar algorithms, the radar measurements nevertheless show a response to soil moisture change, and they can provide useful information on the spatial and temporal variability of soil moisture.

TL;DR: A sampling analysis for a polar-orbiting satellite with 900 km swath width is performed to determine the number of satellite observations over a given surface grid cell during an extended period and suggests an accuracy of 0.1 psu is achievable for global monthly 10 latitude by 10 longitude gridded products.

TL;DR: The design, error budget, and preliminary test results of a 50-56-GHz synthetic aperture radiometer demonstration system are presented and one result suggests a hybrid image synthesis algorithm in which long baselines are processed by a fast Fourier transform and the short baselines have their processing handled by a more precise algorithm which can handle small anomalies among antenna and receiver responses.

TL;DR: The results indicate that passive polarimetric radiometry has a strong potential for global ocean wind speed and direction measurements from space.

TL;DR: A passive/active WS-band (PALS) microwave aircraft instrument to measure ocean salinity and soil moisture has been built and tested and indicated a clear and repeatable salinity signal during these three days, which was in good agreement with the Cape Hatteras ship salinity data.
