Observation‐Informed Machine Learning Convective Scheme: A New Training Strategy

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Machine learning (ML)‐based schemes face challenges in online stability and biases because of the accumulated errors during long‐term integrations. Here, we propose a new ML training strategy for the convection process that provides online corrections to tendencies in a more systematic way with significant improvements in stability and bias ...

First Triple‐Frequency Retrievals of Binned Raindrop Size Distributions

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Our understanding of raindrop size distributions (DSDs) aloft is largely limited, owing to a scarcity of effective measurements. In this study, a two‐step optimal estimation technique is developed for retrieving binned DSDs based on a newly developed vertically‐pointing triple‐frequency radar system. In the first step, we employ the Tridon and

Impacts of Carbon Dioxide Deposition on Martian Near‐Surface Wave Activity

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract A prominent feature of Mars' winter atmosphere is near‐surface baroclinic wave activity. These waves exert strong control on dust storm variability and contribute to transport of heat, momentum, and dust. Using a suite of Mars general circulation model simulations, we investigate an underexplored connection between near‐surface wave activity ...

Pollution‐Clearing Induced Fog Suppression Even Under Extremely Humid Conditions Over North China Plain During 2013–2024

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Fog and haze significantly affect visibility, air quality, and public health. Although haze pollution in the North China Plain has decreased in recent years, its effect on fog formation remains unclear. We find that despite an increase in extremely high‐humidity events, fog frequency has declined, and the fraction of high‐humidity periods that

Hill‐Terrain Modulation of Inland Snow‐Cloud Microphysics: Polarimetric Radar and Balloon‐Borne Particle Imaging Radiosonde Observations

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Snow‐cloud microphysics over inland hills partly resembles that over high mountains, yet exhibits notable differences. During 2024–2025 winter, coordinated observations in Tokamachi City, Niigata Prefecture, Japan, were conducted using four launches of a newly developed balloon‐borne particle‐imaging radiosonde (Rainscope) together with dual X‐
