If you haven’t done so, this is a reminder to submit your abstract for the online LOTUS workshop before Thursday 21 May at https://events.spacepole.be/event/81/abstracts
We encourage you to present your recent results or future plans related to the production, intercomparison or regression analysis of long-term O3 data records & simulations. In order to finalise the agenda we would need a title and a brief abstract of what you would like to share with us during the WebEx session.
We aim at ~15min presentations, but depending on the number of abstracts or topics, the actual time slots may vary in length.
Kind regards,
Daan, Sophie & Irina
