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.

Winds in Collision: high-energy particles in massive binary systems
, 2006 High-resolution radio observations have revealed that non-thermal radio emission in WR stars arises where the stellar wind of the WR star collides with that of a binary companion.

Water Resources Research, Volume 62, Issue 3, March 2026.Abstract Meteorological droughts (persistent precipitation deficits) often, but not always, transition into agricultural droughts (persistent soil moisture deficits). The intensity of agricultural drought, however, can vary for a given precipitation deficit due to a number of catalyzing co‐factors beyond precipitation such as atmospheric evaporative ...

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.
