The stratospheric dynamics journal club consists of a group of about 25 members ranging from first year PhD students to more senior researchers who meet online every 2 weeks to discuss a paper. The size of the group varies depending on the paper being discussed and the various interests of individuals but typically between 6 to 10 members will be present. We meet on Thursdays at 8 am PST, 11 am EST, 1 pm Argentina, 4 pm UK, 5 pm CET, 6 pm Israel for 1.5 hours. Each participant is given a section of the paper to prepare and present. The expectation is that they will be able to explain what is being shown in the figures and to draw attention to any interesting discussion points but no one is expect to be an expert in the subject matter.

Although most of the current members are early career, everyone is welcome including senior researchers.

If you are interested in joining th club, please directly contact Alison Ming at adl33[-ät-]cam.ac.uk

16-17 March 2021, online : 2 half-day virtual sessions via Webex (in the late afternoon, to facilitate participation of Canadian and US colleagues).

The workshop will provide overviews of the different ozone data products generated in Ozone_cci in recent years and of their quality. We will further discuss applications of the ozone data products by international initiatives, for instance for trend assessments, for re-analysis, and for the evaluation of atmospheric models. In addition, we have planned selected talks on key science highlights in recent years.

The European Space Agency Climate Change Initiative aims to realise the full potential of the longterm global Earth Observation archives that ESA, together with its member states, has established over the past 30 years. This workshop focuses on the generation and exploitation of CCI’s multidecadal time series of harmonised and consistent ozone data suitable to assess long-term changes in total ozone, as well as its vertical distribution.

Day 1: Ozone_cci Climate Data Records and Quality Assessment

Presentation by the CCI team of the ozone data records in the CCI portfolio. We discuss their characteristics and illustrate how to obtain and work with these data records. We also provide our assessment of their quality

Day 2: Scientific use of Ozone_cci data

Presentation by researchers outside the CCI team of selected scientific topics and international initiatives, where Ozone_cci data records (can) make an important contribution.
