Microwave radiometry in monitoring and emergency mapping of water seepage and dangerously high groundwaters

Journal of Telecommunications and Information Technology, 2023
Detailed and geo-referenced maps identifying the locations of saturated and dry levees can be produced using microwave radiometric measurements from a light aircraft or helicopter, and integrated with GPS for positioning and orientation. The development

Assimilation of vegetation optical depth retrievals from passive microwave radiometry [PDF]

Hydrology and Earth System Sciences, 2020
Vegetation optical depth (VOD) retrievals from passive microwave sensors provide analog estimates of above-ground canopy biomass. This study presents the development and analysis of assimilating VOD retrievals from X-, C-, and L-band passive microwave ...

Observation of Mountain Waves and Secondary Gravity Waves in the Mesosphere Lower Thermosphere Above Patagonia

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We find observational evidence for mountain waves (MWs) and secondary gravity waves (2GWs) in the OH*(3‐1) layer above Tierra del Fuego, Argentina. On the night of 21–22 May 2018, the Advanced Mesospheric Temperature Mapper (AMTM) obtained temperatures at ∼84 ${\sim} 84$ km.

Preservation of Historically and Scientifically Important Geospatial Data From Venus

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract A large volume of scientifically and historically important data from the early exploration of Venus is not widely available to researchers. Our work is focused on ameliorating this problem with the archival of geospatial data including radar, topography, and radiometry.

Passive Microwave Radiometry and Active Radar Sounding as Complementary Tools for Geophysical Investigations of Icy Ocean Worlds

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Juno Microwave Radiometer (MWR) observations of Europa and Ganymede offer critical insights into the icy shells of these moons ahead of NASA's Europa Clipper and ESA's JUpiter ICy moons Explorer (JUICE) missions. Both missions are equipped with active radar sounders designed to address key unknowns such as ice shell thickness, thermal state ...

Microwave remote sensing of water vapor in the atmosphere [PDF]

Geographica Helvetica
Water vapor in the atmosphere plays a crucial role in climate and in atmospheric processes. Due to its long chemical lifetime it can be used as a tracer for investigations of dynamical processes in the middle atmosphere.

Monitoring Flood Inundation Dynamics From Space

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

Mapping the CMB II: the second flight of the QMAP experiment

, 1998
We report the results from the second flight of QMAP, an experiment to map the cosmic microwave background near the North Celestial Pole. We present maps of the sky at 31 and 42 GHz as well as a measurement of the angular power spectrum covering the l ...
