Structural changes in the shallow and transition branch of the Brewer–Dobson circulation induced by El Niño Structural changes in the shallow and transition branch of the Brewer–Dobson circulation induced by El Niño
The global meridional overturning of mass in the stratosphere, generally known as the Brewer-Dobson circulation (BDC), plays a crucial role in Earth’s climate system by controlling the distributions of atmospheric constituents.
Response of stratospheric water vapor and ozone to the unusual timing of El Niño and the Quasi-Biennial Oscillation disruption of 2015-2016 Response of stratospheric water vapor and ozone to the unusual timing of El Niño and the Quasi-Biennial Oscillation disruption of 2015-2016
Two major modes of climate variability that affect the stratospheric circulation, and consequently trace gas distributions, are the El Niño–Southern Oscillation (ENSO) and the Quasi-Biennial Oscillation (QBO).
On the role of heterogeneous chemistry in ozone depletion and recoveryOn the role of heterogeneous chemistry in ozone depletion and recovery
Conclusive verification that stratospheric ozone destruction is lessening as expected in response to international controls on anthropogenic ozone-depleting substances (ODSs) enacted under the Montreal Protocol is one of today’s atmospheric science imperatives, but robust detection of such ozone “recovery” is complicated by large natural variability.
 Effects of Arctic stratospheric ozone changes on precipitation in the northwestern United StatesEffects of Arctic stratospheric ozone changes on precipitation in the northwestern United States
Changes in stratospheric ozone can induce, via atmospheric radiation balance, stratospheric circulation anomalies.
Evaluating models of stratospheric composition Evaluating models of stratospheric composition
How well do a free-running and “nudged” chemistry climate model reproduce global timeseries of upper atmospheric composition (biases, variability, trends)?
 Mapping the Oxidizing Capacity of the Global Remote TroposphereMapping the Oxidizing Capacity of the Global Remote Troposphere
This new product represents a novel application of existing satellite data and will help us better interpret contemporary trends in the budgets of methane (a potent greenhouse gas) and ozone (a major pollutant and oxidant source).
OMI Tracks Changes in Mexico’s of Offshore Gas Flaring Activity OMI Tracks Changes in Mexico’s Offshore Gas Flaring Activity
Gas flaring from Mexico’s offshore oil fields leads to economic loss and emissions of air pollutants and greenhouse gases, and there are global efforts to reduce gas flaring.
OMI Links Decrease in Acid Deposition to Emission Reduction OMI Links Decrease in Acid Deposition to Emission Reduction in the Eastern U.S.
Introducing a new method using OMI observations to attribute decrease in acid deposition to SO2 emission reduction
>The Nature of Ozone in Deep Convective Clouds The Nature of Ozone in Deep Convective Clouds As Measured from Aura OMI/MLS
OMI satellite measurements reveal for the first time many key features of ozone variability inside deep convective clouds
Trends in Global Tropospheric Ozone Trends in Global Tropospheric Ozone Inferred from a Composite Record of TOMS/OMI/MLS/OMPS Satellite Measurements and the MERRA-2 GMI Simulation
OMI satellite measurements identify increases in tropospheric ozone over Saudi Arabia/India/Southeast Asia and other global regions

The Ozone Monitoring Instrument (OMI) International Team, consisting of Dutch, Finnish and American scientists, was awarded the 2018 William T. Pecora Award by the USGS.
 Nitrogen Dioxide Data to Show A Relationship Between Air Quality Changes & Economic Growth Globally  Nitrogen Dioxide Data to Show A Relationship Between Air Quality Changes & Economic Growth Globally
Satellites offer an unprecedented opportunity to evaluate patterns and trends in air pollution, especially in regions with few or no ground-based monitors.
 The 2018 National Academies’ Decadal Survey Highlights Aura Data to Demonstrate the Power of Satellite Data for Science & Societal Benefit  The 2018 National Academies’ Decadal Survey Highlights Aura Data to Demonstrate the Power of Satellite Data for Science & Societal Benefit
In "Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space”, Aura data were presented as examples of satellite observations used as a global monitoring system for air quality & health and stratospheric ozone.
