The second SPARC/WMO Long-term Ozone Trends and Uncertainties in the Stratosphere (LOTUS) workshop took place in Geneva, September 17-19, 2018 (https://events.oma.be/indico/event/56/overview).
About 30 participants gathered to discuss open issues remaining after publishing the SPARC/WMO LOTUS report that was aimed at providing timely input to the 2018 Ozone assessment.
Model outputs generated by the Theory and Analysis Working Group are now available as netCDF files for individual stations from 1985-2017. They can be downloaded via anonymous ftp at the website ftp://ftp.cpc.ncep.noaa.gov/ndacc/gmi_model_data. The files are generated from a GMI chemistry transport model (CTM) simulation integrated with MERRA2 reanalysis meteorology. They have realistic constituent variability from daily to seasonal timescales.
SHADOZ (Southern Hemisphere ADditional OZonesondes), an NDACC Cooperating Network, is a NASA project to augment and archive balloon-borne ozonesonde launches, and to archive data from tropical and remote operational sites.
The last two SHADOZ newsletters came out in late 2017 (#23) and May 2018 (#24). These, and all previous issues, are available at: https://tropo.gsfc.nasa.gov/shadoz/Newsletter.html.
SHADOZ (an NDACC Cooperating Network) data have been re-processed over the past 2-3 years with four papers documenting the activity and evaluating changes in the data and uncertainties as follows. You may be able to download some of the articles directly from the publisher. Otherwise, all are downloadable at the website: https://tropo.gsfc.nasa.gov/shadoz/SHADOZ_PubsList.html.
