Ground‐Based Microwave Measurements of ClO and O3 Over Scott Base, Antarctica

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract We present measurements from a new microwave instrument that has been deployed at Scott Base, Antarctica, primarily to measure ClO. The new instrument allows for the extension of the time series of lower stratospheric ClO measurements begun in 1996 at this site, while some of the technical improvements offer the possibility of making ...

Determination of low-level temperature profiles from microwave radiometer observations during rain [PDF]

Atmospheric Measurement Techniques
Usually, microwave radiometer observations have to be discarded during rain. The radomes of the receiver antenna get wet, which hampers accurate measurements since the retrieval algorithms to derive atmospheric quantities are not trained for rain events.

Monitoring contamination level on insulator materials under dry condition with a microwave reflectometer [PDF]

, 2016
Current techniques used for monitoring the levels of contamination on high voltage insulators, such as leakage current and infrared, are not effective in dry conditions since they require the surface of the insulator to be wetted by fog, rain or snow. If

Improving Air Quality Simulations in California's San Joaquin Valley Using Land Surface Remote Sensing

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Accurate regional air quality modeling is crucial for the development of effective air pollution mitigation plans. Precisely simulating meteorological conditions, especially planetary boundary layer (PBL) properties, is challenging due to complex land surface conditions.

Improving the altimetric rain record from Jason-1 & Jason-2 [PDF]

, 2010
Dual-frequency rain-flagging has long been a standard part of altimetric data analysis, both for quality control of the data and for the study of rain itself, because altimeters can provide a finer spatial sampling of rain than can passive microwave ...
