A Miniaturized Spectrometer Radiometer Based on MMIC Technology for Tropospheric Water Vapor Profiling
TL;DR: In this article, a ground-based water vapor profiling radiometer is proposed to reduce the mass and volume of microwave remote sensing instrumentation and reduce substantially the necessary operational power consumption and size of the radio-frequency and intermediate-frequency sections.

TL;DR: An observation system simulation experiment was performed in which synthetic examples of retrievals using a network of radiometers were compared with results from the Weather Research and Forecasting model, showing that the 3-D water vapor field can be retrieved with an accuracy of better than 15%-20%.

Effects of foam on ocean surface microwave emission inferred from radiometric observations of reproducible breaking waves
TL;DR: A number of empirical parameterizations of whitecap coverage with wind speed were used to estimate the increase in brightness temperatures measured by a satellite microwave radiometer due to wave breaking in the field of view, providing the first empirically based parameterization with windspeed of the effect of breaking waves and foam on satellite brightness temperatures.
