TL;DR: Surface soil moisture retrieval algorithms based on passive microwave observations, developed and verified at high spatial resolution, were evaluated in a regional scale experiment and showed that soil texture dominated the spatial pattern at this scale.

TL;DR: In this paper, the authors presented an alternative to real aperture measurements of the Earth's brightness temperature from low Earth orbit using a single interferometric measurement, and the noise characteristics of the brightness temperature image produced from the interferometer measurements are discussed.

TL;DR: The Aquarius/SAC-D mission as discussed by the authors was designed to provide monthly global salinity measurements at a similar, scientifically useful accuracy and spatio-temporal resolution, and it came at a time of growing scientific awareness of the need for the data.

TL;DR: Washita'92 was a large-scale study of remote sensing and hydrology conducted on the Little Washita watershed in southwest Oklahoma as discussed by the authors, which included passive microwave observations using an L-band electronically scanned thinned array radiometer ( ESTAR) and surface soil moisture observations at sites distributed over the area.

TL;DR: The ESTAR as mentioned in this paper is a hybrid real-and-synthetic aperture radiometer which employs stick antennas to achieve resolution along track and uses aperture synthesis to achieve resolutions across track.
