Atmospheric science seminar series

Format: web-based using zoom 



Every second week on Tuesdays at 12:15 – 12:45 followed by 15+ minutes for questions/discussions. So, one can sit and eat lunch during the presentations



Anyone can listen/see/participate. The level is between soft and hard science but everyone with a meteorological background including operational forecasters should be able to follow.

Suggestions for additional seminars are more than welcome.

The order of presentations outlined below is the first attempt. We can of course re-order. Please write a mail to Eigil ( if you are unable to present on the day proposed. It can be considered to record the presentations and the subsequent discussions but this has not yet been decided. In any case, this will require a written accept – at least from presenters and people taking part in the discussions (maybe this becomes too complicated?)


  • 27/10 2020: Eigil Kaas (NBI). “Ongoing and upcoming developments/products of the IFS forecast system at ECMWF plus other news from the ECMWF”.
