tropomi on the esa sentinel 5 precursor a gmes mission for global observations of the atmospheric composition for climate air quality and Ozone Layer applications
Remote Sensing of Environment, 2012Co-Authors: J P Veefkind, Ilse Aben, K Mcmullan, H Forster, J W De Vries, Gerard Otter, J Claas, H Eskes, J F De HaanAbstract:The ESA (European Space Agency) Sentinel-5 Precursor (S-5 P) is a low Earth orbit polar satellite to provide information and services on air quality, climate and the Ozone Layer in the timeframe 2015-2022. The S-5 P mission is part of the Global Monitoring of the Environment and Security (GMES) Space Component Programme. The payload of the mission is the TROPOspheric Monitoring Instrument (TROPOMI) that will measure key atmospheric constituents including Ozone, NO2, SO2, CO, CH4, CH2O and aerosol properties. TROPOMI has heritage to both the Ozone Monitoring Instrument (OMI) as well as to the SCanning Imaging Absorption spectroMeter for Atmospheric CartograpHY (SCIAMACHY). The S-5 P will extend the data records of these missions as well as be a preparatory mission for the Sentinel-5 mission planned for 2020 onward. The mission is pre-operational and is the link between the current scientific and the operational Sentinel-4/-5 missions. This contribution describes the science and mission objectives, the mission and the instrument, and the data products. While building on a solid foundation of the heritage instruments, the S-5P/TROPOMI mission is an exciting step forward with a strong focus on the troposphere. This is achieved by a combination of a high spatial resolution and improved signal-to-noise, as well as dedicated data product development. It is anticipated that the S-5 P mission will make a large contribution to the monitoring of the global atmospheric composition, as well as to the scientific knowledge of relevant atmospheric processes. © 2012 Elsevier Inc.

risks to the stratospheric Ozone shield in the anthropocene this article belongs to ambio s 50th anniversary collection theme Ozone Layer
AMBIO: A Journal of the Human Environment, 2021Co-Authors: Susan SolomonAbstract:Crutzen (1974) and Crutzen and Ehhalt (1977) presented two key papers in Ambio that in Ambioexemplify how science first revealed to humankind the potential for damage to our Ozone shield in the Anthropocene. Crutzen's (1974) review is a sweeping summary of the risks to the Ozone Layer from supersonic aircraft, chlorofluorocarbons, as well as nuclear weapons testing and nuclear war. Crutzen and Ehhalt (1977) described how the nitrous oxide produced from fertilizers could pose another threat to the stability of the stratospheric Ozone Layer. The two papers are part of a body of influential scientific work that led to the pioneering Montreal Protocol to Protect the Earth's Ozone Layer to phase out production of chlorofluorocarbons (in 1987), as well as national decisions that slowed or stopped production of supersonic planes (in the 1970s). They remain guideposts today for ongoing international negotiations regarding reducing emissions from fertilizer and limiting nuclear testing.

Unfinished business after five decades of Ozone-Layer science and policy
Nature Communications, 2020Co-Authors: Susan Solomon, Joseph Alcamo, A R RavishankaraAbstract:The Montreal Protocol has begun to heal the Antarctic Ozone hole and avoided more global warming than any other treaty. Still, recent research shows that new unexpected emissions of several chlorofluorocarbons, carbon tetrachloride, and hydrofluorocarbons, are undermining the Protocol’s success. It is time for policymakers to plug the holes in the Ozone hole treaty.

emergence of healing in the antarctic Ozone Layer
Science, 2016Co-Authors: Susan Solomon, Diane J Ivy, Doug Kinnison, Michael J Mills, Ryan R Neely, Anja SchmidtAbstract:Industrial chlorofluorocarbons that cause Ozone depletion have been phased out under the Montreal Protocol. A chemically driven increase in polar Ozone (or “healing”) is expected in response to this historic agreement. Observations and model calculations together indicate that healing of the Antarctic Ozone Layer has now begun to occur during the month of September. Fingerprints of September healing since 2000 include (i) increases in Ozone column amounts, (ii) changes in the vertical profile of Ozone concentration, and (iii) decreases in the areal extent of the Ozone hole. Along with chemistry, dynamical and temperature changes have contributed to the healing but could represent feedbacks to chemistry. Volcanic eruptions have episodically interfered with healing, particularly during 2015, when a record October Ozone hole occurred after the Calbuco eruption.

Indirect radiative forcing of the Ozone Layer during the 21st century
Geophysical Research Letters, 2007Co-Authors: Robert W. Portmann, Susan SolomonAbstract:[1] The response of a coupled two-dimensional radiative-chemical-dynamical model to possible 21 st century changes of the greenhouse gasses (GHGs) carbon dioxide, nitrous oxide and methane are explored using a range of IPCC marker scenarios of GHG emissions. The changes to the Ozone Layer caused by these GHGs are found to be relatively large (e.g., up to 5% global mean column Ozone changes and 30% local changes for CO 2 using the IPCC A2 scenario between 2000 and 2100) and the mechanisms for these changes are discussed. The Ozone changes are compared to the recovery of Ozone due to expected decreases in chlorine containing compounds. Since carbon dioxide, nitrous oxide, and methane affect Ozone they induce an indirect radiative forcing in addition to their direct radiative forcing. These indirect radiative forcings are computed using a combination of accurate line-by-line and band radiative transfer models and are compared to the radiative forcing of Ozone during the 1979-2000 time period. Although the changes in Ozone are large at some altitudes over the 2000-2100 time horizon, the range of associated future indirect radiative forcings from Ozone over the range of IPCC scenarios are found to be -0.1 to 0.1 W m -2 , which is small compared with the corresponding range of total direct radiative forcing of 2.2 to 6.2 W m -2 for these GHGs over this time horizon.
