Estimating the summertime tropospheric ozone distribution over North America through assimilation of observations from the Tropospheric Emission Spectrometer [PDF]

, 2008
We assimilate ozone and CO retrievals from the Tropospheric Emission Spectrometer (TES) for July and August 2006 into the GEOS-Chem and AM2-Chem models.

Antarctic Ozone hole was better than average in 2010 [PDF]

, 2016
This false color image of ozone total column amounts, based on UV and Infrared (IR) measurements by the NOAA SBUV/2 and HIRS instruments, shows the ozone hole (in red) on 26 September 2010, when analysis determined it to be at its maximal seasonal extent

Fingerprints of the cosmic ray driven mechanism of the ozone hole

AIP Advances, 2021
There is long research interest in electron-induced reactions of halogenated molecules. It has been two decades since the cosmic-ray (CR) driven electron-induced reaction (CRE) mechanism for the ozone hole formation was proposed. The derived CRE equation

The vertical distribution of ozone instantaneous radiative forcing from satellite and chemistry climate models [PDF]

, 2011
We evaluate the instantaneous radiative forcing (IRF) of tropospheric ozone predicted by four state-of-the-art global chemistry climate models (AM2-Chem, CAM-Chem, ECHAM5-MOZ, and GISS-PUCCINI) against ozone distribution observed from the NASA ...

On the use of satellite observations to fill gaps in the Halley station total ozone record [PDF]

Atmospheric Chemistry and Physics, 2021
Measurements by the Dobson ozone spectrophotometer at the British Antarctic Survey's (BAS) Halley research station form a record of Antarctic total column ozone that dates back to 1956.

Reconciliation of essential process parameters for an enhanced predictability of Arctic stratospheric ozone loss and its climate interactions : (RECONCILE) ; activities and results [PDF]

, 2013
The international research project RECONCILE has addressed central questions regarding polar ozone depletion, with the objective to quantify some of the most relevant yet still uncertain physical and chemical processes and thereby improve prognostic ...

The Antarctic ozone hole during 2015 and 2016 [PDF]

Journal of Southern Hemisphere Earth Systems Science, 2019
We reviewed the 2015 and 2016 Antarctic ozone holes, making use of a variety of ground-based and spacebased measurements of ozone and ultraviolet radiation, supplemented by meteorological reanalyses.

Transport and mixing processes during the Antarctic ozone increase

Antarctic Record, 2010
The 44th Japanese Antarctic Research Expedition (JARE-44) performed intensive ozonesonde observations at Syowa Station (69.0゜S, 39.6゜E) from June 2003 through January 2004 to clarify the time evolution and mechanism of the Antarctic ozone hole ...

Chemical ozone loss in the Arctic winter 1991–1992 [PDF]

, 2007
Chemical ozone loss in winter 1991–1992 is recalculated based on observations of the HALOE satellite instrument, Version 19, ER-2 aircraft measurements and balloon data.
