Measuring and Mapping Urban NO2 Pollution Heterogeneity Using a Custom Pandora Spectrometer Experiment and Observations From TEMPO

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Nitrogen dioxide (NO2) is a primary pollutant present at high concentrations in urban areas. Ground based measurements remain sparse and satellite observations rely on retrievals, so understanding intraurban, diurnal‐scale changes in NO2 is challenging.

Microphysics and Kinematics of a High Flash Rate Storm With a Bottom‐Heavy Charge Structure

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract An atypical thunderstorm with unusual lightning and charge structure characteristics propagated through Cordoba province, Argentina, during the austral warm season in late 2018. This storm exhibited echo tops near 10.5 km, with high lightning activity concentrated at low altitudes.

Instrumental Artefacts Can Reverse Apparent Lightning–Climate Trends

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Lightning is an Essential Climate Variable, yet long‐term detection records may be compromised by changes in detection technology. Using more than three decades of Austrian lightning observations (1992–2024), we show that instrumental artefacts can reverse the apparent sign of lightning–climate trends.

Detection and Analysis of an Upward Jet‐Like Electrical Discharge Intercepting a High‐Altitude Research Aircraft

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract During a 2023 field campaign, a NASA ER‐2 research aircraft intercepted an upward jet‐like electrical discharge at 20 km altitude over an intense tropical thunderstorm. This event was analyzed using airborne multispectral optical sensors, electric field mills, X‐band radar, passive microwave, and ground‐based radio networks.

Dependence of Neutralized Charge Amount on Meteorological Conditions in Summertime Lightning Discharges in Japan

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Lightning discharges in Gunma Prefecture, Japan, from June–September 2023 were analyzed to explore the dependence of the neutralized charge amount on cloud structures embedded in weather systems, mainly based on in situ measurements of the ground‐based electric field, radar and satellite remote sensing, and numerical simulations using a bulk ...
