Topographic Scattering of Internal Waves in the Presence of a Steady Surface Current

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Wave–topography interaction is one of the primary mechanisms through which internal wave energy cascades to small length scales, eventually leading to turbulent diffusion and mixing in the oceans. Precise diffusivity parametrizations are crucial for modeling oceanic flows accurately.

Constraining Greenhouse Gas Cycling and Emissions in Africa's Largest Humic Lake

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Humic tropical lakes and wetlands are globally important sources of atmospheric greenhouse gases (GHGs). However, mechanistic insight into GHG cycling in such systems remains limited—especially in understudied central Africa. To address this, here we measured high‐, falling‐, and low‐water seasonal concentrations and isotopic compositions of ...

Double‐Peaked Hyperspectral Features at 710 and 800 nm for Monitoring Coastal Chlorophyll‐α Concentrations From Space

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract The concentration of chlorophyll‐α $\alpha $ has been estimated from sea color, primarily based on the reflectance ratio between the blue and green spectral bands in multiband images obtained by satellite optical sensors. However, this method is only effective in open, clear water and cannot be reliably applied to shallow coastal waters.

Extending the Atmospheric Radiative Transfer Simulator (ARTS) to Shortwave Radiation

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Atmospheric Radiative Transfer Simulator (ARTS) is an open source general purpose radiative transfer model used for a wide range of applications from remote sensing to the interaction of climate and radiation. In the past, it was confined to the microwave and infrared spectral range, as ARTS could not simulate the interaction of solar ...

Waning light, waxing pain: The lunar cycle's association with migraine headache occurrence

Headache: The Journal of Head and Face Pain, Volume 66, Issue 3, Page 584-594, March 2026.
Plain Language Summary While migraine headaches can be hard to predict, some patients believe headaches are connected to the moon‘s phases. Our research showed that migraine attacks were 34% more likely to occur during the new moon than during the full moon.
