Effect of stratosphere-troposphere exchange on the future tropospheric ozone trend [PDF]

, 2003
This paper investigates the impact of circulation changes in a changed climate on the exchange of ozone between the stratosphere and the troposphere. We have identified an increase in the net transport of ozone into the troposphere in the future climate ...

Projected 5G Interference Can Degrade Passive Microwave Radiance Assimilation and Alter High‐Impact Weather Forecasts

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Passive microwave radiances near 23.8 GHz constrain lower‐tropospheric water vapor, but this protected window lies adjacent to fifth‐generation (5G) telecommunications spectrum. We quantify how projected terrestrial 5G leakage propagates through county‐scale deployment projections, directional antenna geometry, synthetic contamination of AMSU ...

Impact of climate variability on tropospheric ozone [PDF]

, 2007
A simulation with the climate–chemistry model (CCM) E39/C is presented, which covers both the troposphere and stratosphere dynamics and chemistry during the period 1960 to 1999.

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 ...

Sulfur Dioxide Point Sources Remain Important for Daytime Plume‐Scale New Particle Formation in the United States: Case Study for Gary, Indiana During the Summer 2023 AEROMMA Aircraft Campaign

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Plumes from sulfur dioxide (SO2) point sources have been shown to be significant contributors to new particle formation (NPF), but SO2 emissions in the United States (US) have decreased drastically by ∼10× since the early 2000s. We present observations of plume‐scale NPF from SO2 point sources over the industrial hub in Gary, Indiana and ...

The Effect of Modified UNBabc Mapping Function On the Improvement of Global Positioning System Tropospheric Delay [PDF]

, 2009
Global Positioning System (GPS] tropospheric delay refers to the refraction of the GPS signal as it passes through the'neutral atmosphere from the satellite to the earth, which causes longer distance traveled by the signal. The issue of atmospheric delay

Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.
