Observation And Modelling Of Stratospheric Filaments During The Pico3 Campaign
Abstract
The Meso-NHC model (Meso-scale Non-Hydrostatic and Chemical model) is used to study a Stratosphere - Troposhere Exchange process during the formation of strato- spheric filaments consecutive to planetary wave breaking events. We use a grid-nested simulation with horizontal resolutions of 30 km and 10 km, with a vertical resolu- tion of 300 m. The model is initialised with ARPEGE (Météo-France) analyses for meteorological variables and with MOCAGE (Météo-France) analyses for chemical variables. The data set used to evaluate the performances of the model is the PICO3 data set gathered during an airborne campaign over NW Africa with the french jet aircraft equiped with in-situ measurements of O3 and CO and an airborne O3 lidar. Results from a simulation of a case study will be described.
