Constraining the hydroxyl radical in the tropicsUsing satellite observations of its drivers are the first steps toward assessing the feasibility of a global observation strategy.
Combined catalogue of sulfur dioxide emissionsSulfur dioxide measurements from three satellite instruments (OMI-OMPS-TROPOMI) were used to update and extend the previously developed global catalogue of large anthropogenic sulfur dioxide emission sources and degassing volcanoes
Evolution of the Hunga Tonga-Hunga Ha’pai sulfate aerosol and water vapor plumesMeasurements from the Aura Microwave Limb Sounder (MLS) revealed that a distinct aerosol and water vapor layer formed in the stratosphere.
Earth’s ozone layer on track to recover within decadesMicrowave Limb Sounder (MLS) data and scientists make key contributions to 2022 WMO Ozone Assessment.
Signatures of Anomalous Stratospheric Polar Vortex TransportThe 2019/2020 Arctic stratospheric polar vortex was exceptionally strong and long-lived, leading to the largest chemical ozone loss on record in the Arctic.
