Correction for the Attenuation Due to Atmospheric Gas and Stratiform Clouds in Triple-Frequency Radar Observations of the Microphysical Properties of Snowfall

open access: yesRemote Sensing, 2023
For triple-frequency radar, the attenuation attributed to atmospheric gases and stratiform clouds is diverse due to different snowfall microphysical properties, particularly in regions far from the radar.

Numerical study on signatures of atmospheric convective cells in radar images of the ocean

open access: yes, 1999
Current and wind variations at the ocean surface can give rise to a modulation of the sea surface roughness and thus become visible in radar images. The discrimination between radar signatures of oceanic and atmospheric phenomena can be quite difficult ...

Pioneer Venus atmospheric observations

open access: yesPhilosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1981
Abstract Some selected results from the scientific experiments on the recent Pioneer missions to Venus are reviewed, with particular emphasis on data from the infrared remote sensing experiment on the orbiter. Various aspects of the structure, dynamics and energy budget of the atmosphere, as revealed by the measurements, are presented

Large Amounts of Water Vapor Were Injected into the Stratosphere by the Hunga Tonga–Hunga Ha’apai Volcano Eruption

open access: yesAtmosphere, 2022
The Hunga Tonga–Hunga Ha’apai (Tonga) injected only small amount of SO2 into the stratosphere, while our analyses of the Microwave Limb Sounder (MLS) measurements show that a massive amount of water vapor was directly injected into the stratosphere by ...
