Particulate Pollution and its Climate Impacts During the COVID-19 Pandemic
The impacts of COVID-19 on short-lived pollutants highlight the predominant influence of the transportation sector and the resulting changes in regional climates and ecosystems.
Need for Better Accounting of CFC-12 Emissions from China
New observations show that bottom-up tracking of CFC-12 emissions from China are underestimated, illustrating the need for better accounting for reductions from the Montreal Protocol.
What Happens in the Troposphere Doesn’t Stay in the Troposphere
A new study suggests that spillover of tropospheric ozone is affecting measurements of stratospheric ozone recovery more than previously realized.
A Fast and Accurate Open-Source Atmospheric Transport Model
A new zonally-averaged atmospheric transport model will be useful for estimating emissions of ozone-depleting substances and greenhouse gases.
Uncertainty Abounds in Seeding the Sky to Fight Climate Change
Some scientists have suggested injecting solid particles such as alumina, calcite, or even diamonds into the atmosphere to temporarily limit climate warming. But new research shows there are still big unknowns.
Certaines plantes laissent une empreinte digitale chimique sur un gaz qui appauvrit la couche d’ozone
Une nouvelle étude, la première dans son genre, suggère qu’il serait possible de recourir à une analyse isotopique pour localiser les sources et les puits de chlorométhane dans l’atmosphère.
Plants Leave Chemical Fingerprints on an Ozone-Depleting Gas
A first-of-its-kind study suggests that isotope analysis could be used to pinpoint sources and sinks of atmospheric methyl chloride.
