Enhancing Environmental Monitoring in Poland: Leveraging Sentinel Satellite Data through the CAMS National Collaboration Programme

Copernicus provides a wide variety of services covering different topics, starting from Atmosphere through Marine, Land, Climate Change, Security and Emergency.Satellite observations on atmospheric composition, complementary to Copernicus Atmosphere Monitoring Service (CAMS), become increasingly available. Unfortunately, analysis or even opening of satellite data in their native formats prove to be challenging in communities other than scientific.Functionalities, data products, and analysis provided to users on the CAMS website are mainly at the global and European scales. It has been recognized that usage of those services and data they provided by Member States are rather unsatisfactory. Therefore, ECWF prepared CAMS National Collaboration Programmes for member states to improve the uptake of CAMS products at the national, regional and local levels, responding to regulatory needs coming from public administration, NGO's and other interested parties. Institute of Environmental Protection – National Research Institute is responsible for the provision and development of the CAMS National Collaboration Programme for Poland.We will present the usage of prepared averaged products derived from Sentinel 5P AER AI, Sentinel 5P NO2, and S5P HCHO data in investigating transport episodes connected with wildfires or desert dust over the Polish region. We have investigated data from 2019 to 2023 for both RPRO and OFFL Sentinel 5P products.We will also discuss the potential usage of other products being tailored and developed during the CAMS NCP Poland project, which have been indicated during the preliminary communication phase via survey  and discussion on 1-st User and stakeholder meeting. The study's outcome would also be important for the HE CAMEO project, where we investigate potential benefits from the assimilation of satellite data to the regional models.
