Improving GNSS precise point positioning with tropospheric constraints from data-driven numerical weather prediction model

Geo-spatial Information Science
Accurate priori tropospheric knowledge is advantageous for Global Navigation Satellite System (GNSS) precise point positioning (PPP), which significantly influences both convergence time and the accuracy of tropospheric delay estimations.

Post‐Monsoon Pollution Events in the Indo‐Gangetic Plain Using 18 Years [2007–2024] of IASI Carbon Monoxide Satellite Measurements

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract In recent years, the Indo‐Gangetic Plain (IGP) has experienced recurring intense air pollution episodes during the post‐monsoon season (October–November), posing significant health risks to millions of inhabitants. These pollution events coincide with agricultural waste burning, emitting large quantities of carbon monoxide (CO) into the ...

Kernel‐Based Estimation of Stratospheric Aerosol Radiative Effects From Volcanic and Wildfire Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract To facilitate the quantification of the stratospheric aerosol direct radiative effect (ARE), this study develops a suite of aerosol kernels based on Modern‐Era Retrospective Analysis for Research and Applications, Version 2 reanalysis data. The kernels comprise a five‐dimensional data set that includes latitude, longitude, time, wavelength ...

Evaluation of CAM Single‐Column Models in Simulating Convectively Coupled Rossby Gravity Waves During TRMM‐KWAJEX

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Leveraging observational data from the TRMM‐KWAJEX field campaign, which captures the evolution of mixed Rossby‐gravity (MRG) waves, this study evaluates how parameterization schemes influence convectively coupled MRG waves in the Community Atmospheric Model single‐column framework (SCAM).

An Analytical Model of the Lifecycle of Tropical Anvil Cloud Radiative Effects

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Satellite observations and numerical simulations show that the small net Cloud Radiative Effect (CRE) of tropical anvil clouds results from a near‐cancellation between large but opposing longwave (LW) and shortwave (SW) components over the cloud's lifecycle.

Thousand Years of Nitrogen Oxide Sources in Western Europe: Evidence From Nitrogen Stable Isotopes (δ15N) of Nitrate in a Mont Blanc Ice Core

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Nitrogen stable isotopes (δ15N) of ice core nitrate (NO3−) are often subject to diverse interpretations associated with changes in nitrogen oxide (NOx) sourcing, atmospheric reactions, and/or post‐depositional processes. Here, an ice core from Mont Blanc (French Alps) was analyzed to investigate the δ15N(NO3−) record over the past 1,000 years.

Amplifying Variability of the Southern Annular Mode in the Past and Future

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The Southern Annular Mode (SAM) is the dominant mode of atmospheric variability in the Southern Hemisphere extratropics. While its long‐term positive trend is well‐documented, changes in the amplitude of SAM variability remain poorly understood. Based on reanalysis data and surface‐station observations, we demonstrate that the amplitude of SAM
