Distinct Efficacy of Regional Methane Emissions in Affecting Global and Regional Concentrations: An Emission‐Driven CESM2 Modeling Study With Methane Tags

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract The newly developed emission‐driven capability of CESM2 allows methane concentrations to be more realistically simulated based on emissions, transport, and atmospheric chemistry, rather than being prescribed as lower boundary conditions as in most previous global Earth system modeling studies.

Reanalysis comparisons of upper tropospheric–lower stratospheric jets and multiple tropopauses [PDF]

, 2017
The representation of upper tropospheric–lower stratospheric (UTLS) jet and tropopause characteristics is compared in five modern high-resolution reanalyses for 1980 through 2014. Climatologies of upper tropospheric jet, subvortex jet (the lowermost part

Assessment of MERRA-2 Land Surface Energy Flux Estimates [PDF]

In MERRA-2, observed precipitation is inserted in place of model-generated precipitation at the land surface. The use of observed precipitation was originally developed for MERRA-Land(a land-only replay of MERRA with model-generated precipitation ...

Dust Decline Amplifies High‐Cloud Ice‐to‐Liquid Transition and Buffers the Radiative Feedback Under Warming

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The response of the cloud phase to global warming is a critical yet poorly constrained component of Earth's climate sensitivity. While rising temperatures drive a thermodynamic transition from ice to liquid clouds, the role of ice‐nucleating particles in modulating this shift remains underexplored.

The Impact of MERRA-2 and CAMS Aerosol Reanalysis Data on FengYun-4B Geostationary Interferometric Infrared Sounder Simulations

Remote Sensing
Aerosols significantly impact the brightness temperature (BT) in thermal infrared (IR) channels, and ignoring their effects can lead to relatively large observation-minus-background (OMB) bias in radiance calculations. The accuracy of aerosol datasets is

Discrepancies in the Simulated Global Terrestrial Latent Heat Flux from GLASS and MERRA-2 Surface Net Radiation Products

Remote Sensing, 2020
Surface all-wave net radiation (Rn) is a crucial variable driving many terrestrial latent heat (LE) models that estimate global LE. However, the differences between different Rn products and their impact on global LE estimates still remain unclear.

Dietary Polyphenols in Non‐Communicable Chronic Diseases: Neuro–Enteric Mechanisms, Multi‐Omics Biomarkers and Translational Opportunities

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
This illustration highlights how dietary polyphenols from foods like berries, grapes, and green tea travel through the gut, where microbiota transform them into bioactive metabolites. These metabolites pass into the bloodstream, strengthen the gut barrier, and ultimately reach the brain, supporting neuroprotection through antioxidative and anti ...

Comparison of ozone profiles from DIAL, MLS, and chemical transport model simulations over Río Gallegos, Argentina, during the spring Antarctic vortex breakup, 2009 [PDF]

, 2017
This study evaluates the agreement between ozone profiles derived from the ground-based differential absorption lidar (DIAL), satellite-borne Aura Microwave Limb Sounder (MLS), and 3-D chemical transport model (CTM) simulations such as the Model for ...

Flood Risk Management Using Representative Hillslopes: Insights From a Historical Flood in Southwest Germany

Hydrological Processes, Volume 40, Issue 5, May 2026.
A coupled hydrologic and hydraulic modelling framework relying on representative hillslope models and scaled using hydraulic routing schemes is proposed to simulate Hortonian overland flow at intermediate scales. Using a reconstructed historic summer storm in southwest Germany (1994), we show how hillslope scale nature‐based flood prevention measures ...

TURAAB: A 34‐Year Dust and Atmospheric Regional Reanalysis for the Middle East, North Africa and Mediterranean—First Insights

Meteorological Applications, Volume 33, Issue 3, May/June 2026.
TURAAB: A 34‐year dust and atmospheric regional reanalysis for the Mediterranean–MENA region. We present TURAAB, a 34‐year, 6‐km regional reanalysis integrating meteorology and dust for the Mediterranean–MENA domain. The system demonstrates good behavior, aligning closely with observational and reanalysis products. TURAAB provides a high‐value resource
