Large Drifter Experiment in the Western Mediterranean Sea Reveals Dynamical Versus Noise Contributions in SWOT‐KaRIn Sea Level

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The wide‐swath altimeter Surface Water and Ocean Topography (SWOT) provides unprecedented two‐dimensional sea‐level observations, whose ability to capture upper‐ocean dynamics requires assessment. The dynamically balanced signal and noise contributions in SWOT‐KaRIn Level‐3 (L3) sea level products are here originally quantified and contrasted ...

On the Peculiar Properties of Extremely Low Frequency Lightning Generated Whistlers Detected at Low Earth Orbit Altitudes Close to the Magnetic Equator

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Lightning strikes generate broadband electromagnetic signals. At Extremely Low Frequencies (ELF), these signals partly leak into the ionosphere and produce so‐called Lightning Generated (LG) whistlers that the Absolute Scalar Magnetometers on board the ESA Swarm satellites can detect.
