New publication in Atmospheric Chemistry and Physics

14th December 2022

A new study by Nützel et al. on the “Climatology and variability of air mass transport from the boundary layer to the Asian monsoon anticyclone” is published in the EGU open access journal “Atmospheric Chemistry and Physics”. The Asian monsoon anticyclone is studied by using backward trajectories on reanalysis data for 14 northern summer seasons. Furthermore, forward trajectories from a free- running chemistry-climate model (CCM) simulation with parameterised Lagranigan convection in the EMAC-ATTILA model are analysed.

11th EMAC Symposium will be held in Mainz

30th November 2022

The 11th EMAC Symposium will be on 9th – 11th May 2023 in Mainz. The host institution will be Max Planck Institute for Chemistry. Please mark your calendar, updates and details will follow on the website and via the MESSy mailinglist! We are looking forward to interesting presentations and fruitful discussions at the beautiful Rhine.

New publication in Atmospheric Measurements Techniques

9th June 2022

Pérez-Invernón et al. study the NO_x production of single lightning flashes in the Pyrenees and the Ebro Valley in their publication “Quantification of lightning-produced NO_x over the Pyrenees and the Ebro Valley by using different TROPOMI-NO₂ and cloud research products” published in the Open Acess EGU journal “Atmospheric Measurements Techniques”. They use vertical mixing ratio profiles of NO, NO₂, NO_x, LNO_x and LNO₂ extracted from EMAC simulations with and without lightning for calculation of the LNO_x air mass factor.

New publication in Nature

2nd May 2022

The article “Synergistic HNO₃–H₂SO₄–NH₃ upper tropospheric particle formation” by Mingyi Wang et al. has been published in Nature as Open Access. The authors use the global model EMAC in parts of their study for simulation of particle formation with efficient vertical transport of ammonia into the upper troposphere during the Asian monsoon.
