SWOT Mission Validation of Sea Surface Height Measurements at Sub‐100 km Scales

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract After two decades of development, the Surface Water and Ocean Topography (SWOT) mission launched on 16 December 2022, pioneering the use of Ka‐band Radar Interferometry (KaRIn) for measuring water surface elevation and achieving two‐dimensional altimetry on two 50 km swaths separated by a 20 km nadir gap.

Field‐Aligned Proton Beams Upstream of the Martian Bow Shock: First Observations

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract We report fast sunward‐propagating energetic proton field‐aligned beams (FABs) observed about one Mars radius upstream of the Martian bow shock, recorded by the Solar Wind Ion Analyzer instrument on the MAVEN spacecraft. The velocity distributions show that all the beams have a bulk parallel speed vB=(1.35±0.21)VS ${v}_{B}=(1.35\pm 0.21){V}_{S}

Solar Terminator Waves Revealed as Dominant Features of Upper Thermospheric Density

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Observations of solar terminator waves (STWs) in thermospheric mass density (TMD) measurements above 500 km reveal STWs as dominant features of the upper thermosphere. While previous investigations have shown that STWs in the middle‐lower thermosphere have amplitudes on the order of 6%–8% of the background TMD in that region, this study shows ...
