Description
AerGOM is a retrieval algorithm that was specifically designed to retrieve stratospheric aerosol extinction from the Global Ozone Monitoring by the Occultation of Stars (GOMOS) experiment that was launched onboard Envisat and provided measurements of the Earth atmospheric limb between 2002 and 2012.
While AerGOM retrieves simultaneously aerosol extinction, ozone, nitrogen dioxide and nitrogen trioxide for every night-time occultation measurements (Level 2), the resulting dataset of aerosol extinction is used to produce gridded aerosol datasets (Level 3) with a 5-day time resolution, 5-degree latitude resolution and 60-degree longitude resolution. This dataset, distributed in the framework of the Copernicus Climate Change Service (C3S) and referenced as C3S-GOMOS, can be used for modelling applications, and two such applications are presented in this communication.
The first one is the use of C3S-GOMOS (V. 4.00), to contribute to the reconstruction of a comprehensive inventory of spatially resolved sulfur injections by volcanic eruptions based on the EMAC chemistry-climate model (EMAC5/MESSy Atmospheric chemistry).
More recently, C3S-GOMOS (V. 4.00) has been used for the validation of the Integrated Forecasting System (IFS) of the Copernicus Atmospheric Monitoring Service (CAMS), and more particularly the stratospheric extension of the IFS-AER model, which is the scope of the current CAMS2_35 project.
This communication will present the latest news about the development of AerGOM and C3S-GOMOS, as well as an overview of these two model-related applications.
