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

open access: yesJournal 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 ...

First Aircraft‐Based VOC Measurements Using Thermal Infrared Remote Sensing: Mapping Fire Plumes With the Scanning High‐Resolution Interferometer Sounder (S‐HIS)

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Wildfires emit volatile organic compounds (VOCs) that contribute to ozone and aerosol pollution. Quantification is challenged by the diversity of emitted species and by their complex dependence on fire characteristics, with scarce field observations available for model evaluation.

Spectral Outgoing Longwave Radiation Derived From the Polar Radiant Energy in the Far Infrared Experiment (PREFIRE) Measurements: Algorithms and Validations

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract The far‐infrared (>16 μm) spectrum plays a crucial role in Earth's radiation budget but was rarely observed from space before 2024. Two Polar Radiant Energy in the Far Infrared Experiment (PREFIRE) satellites, PREFIRE2 (SAT‐2) and PREFIRE1 (SAT‐1), were launched in 2024.

Solar Soft X‐Ray Proxy Derived From Observed Auger Photoelectrons by MGS and a 1999–2006 Flare Catalog at Mars

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This study uses a novel approach to infer the solar soft X‐ray (SXR) irradiance from Auger photoelectron fluxes. Solar SXR irradiance is highly variable, particularly during solar flares. Solar SXR photons at ∼< ${\sim} < $2.5 nm produce oxygen Auger photoelectrons by photoionizing atmospheric constituents. More specifically, we derive the fit

The operational processing of wind estimates from cloud motions: Past, present and future [PDF]

open access: yes
Current NESS winds operations provide approximately 1800 high quality wind estimates per day to about twenty domestic and foreign users. This marked improvement in NESS winds operations was the result of computer techniques development which began in ...

Dawn‐Side Anomaly in Sudden Geomagnetic Field Responses to Solar Wind Pressure Discontinuities During the 10 May and 10 October 2024 Geomagnetic Storms

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Interactions of solar wind dynamic pressure (SWDP) discontinuities with Earth's magnetosphere cause geomagnetic Sudden Commencements (SCs). Typically, positive/negative SCs occur at low latitudes due to enhancements/reductions in SWDP.
