Satellite‐Derived Leaf Photosynthetic Capacity Data Set Improves Atmospheric Inversion of Terrestrial Carbon Fluxes

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Accurately estimating the terrestrial carbon sink is crucial for understanding the global carbon cycle. Here, we examine how different parameterizations of the key leaf photosynthetic capacity parameter, namely the maximum Rubisco carboxylation rate normalized to 25°C (Vcmax25), influence terrestrial carbon flux estimates within an atmospheric

Drying Effect of Landfalling Tropical Cyclones

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The high precipitation efficiency of tropical cyclones (TCs) is theorized to dehydrate the atmosphere, a process with important climate implications that has yet to be confirmed by direct observational evidence. Using satellite and reanalysis data, this study statistically examines the drying effect of landfalling TCs. Results indicate a local

Machine Learning Eliminates Reanalysis Warm Bias and Reveals Weaker Winter Surface Cooling Over Arctic Sea Ice

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The surface energy budget governs Arctic sea‐ice growth/melt, yet observations are sparse, and reanalysis data sets suffer from systematic biases. Here, we train a neural network with observational data to bias‐correct hourly ERA5 fluxes over Arctic ice‐covered regions (≥70°N; sea‐ice concentration >80%) for 1994–2024.

Enhanced Solar Radiation Attenuation in the Arctic Shelf Driven by Warming‐Induced Terrestrial Inputs

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Arctic warming accelerates permafrost thaw and coastal erosion, increasing terrestrial material transport to the ocean. Using Moderate Resolution Imaging Spectroradiometer (MODIS) data (2002–2023), we report a widespread increase in the diffuse attenuation coefficient Kd(490) across Arctic shelves since 2018, notably in the Laptev and Kara ...

Understanding Drought‐Induced Soil Moisture Feedback on Atmospheric Circulation: Observations and Simulation Experiments of the 2020 Western U.S. Drought

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract This study examines the large‐scale atmospheric response to reduced evapotranspiration during droughts in the Western U.S., using an observation‐based regression method and numerical experiments with a global climate model. We found that Western U.S.

Statistical Characteristics of Environments of Precipitating Mesoscale Convective Systems During the Pre‐Summer Season Over South China

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Mesoscale convective systems (MCSs) are known to induce heavy rainfall and pose significant weather hazards in tropical and mid‐latitude regions. Understanding the environmental conditions of MCSs is essential for improving model simulations and operational precipitation forecasts.

Accuracy assessment of temperature trends from ERA5 and ERA5-Land

Science of the Total Environment, 2023
Many environmental processes and ecological systems are being affected by the warming temperatures as a result of climate change. To correctly identify and attribute the uncertainty estimates in these systems, an investigation of temperature trend signal existing in the datasets that are used to study such systems is necessary. In this study, the trend
