Yesterday and today, @esiwace is celebrating its 2nd General Assembly virtually 🤩 🙏Big attendance and very nice invited talks from CASTIEL2 @HPCCoE , @ISENES_RI and the HANAMI project.
End of a very productive week meeting @ISSIBern - four very exciting papers planned to come out over the next year or so based on our work at this and our previous team meeting last year. Thanks to ISSI and all the other Team members!
New preprint out today by Emily Lear @UniofBath @bathenganddes and co-authors including myself, @LarsGetThrough , and INna Polichtchouk @ECMWF : essopenarchive.org/users/591721/a…
New development and technical paper: Improved representation of volcanic sulfur dioxide depletion in Lagrangian transport simulations: a case study with MPTRAC v2.4 doi.org/10.5194/gmd-16…
New paper 'Variability and trends of the tropical tropopause derived from a 1980–2021 multi-reanalysis assessment' by Zou et al. Congratulations Ling! frontiersin.org/articles/10.33…
New research article: Lagrangian transport simulations using the extreme convection parameterization: an assessment for the ECMWF reanalyses doi.org/10.5194/acp-23…
