Satellite data provides an opportunity to monitor the atmosphere. One satellite suitable for monitoring is Copernicus Sentinel-5P. This satellite enables atmospheric measurements and to map gases such as nitrogen dioxide, ozone, sulphur dioxide, methane, carbon monoxide, formaldehyde and aerosols. As an example below is a map showing the change of nitrogen dioxide concentrations over Italy in 2019.

All those gases affect the health of human beings. Terramonitor is part of HEDIMED project that deals with immune-mediated diseases including type 1 diabetes, celiac disease, allergy and asthma. One part of the project is to study the impact of air quality on immune-mediated diseases.
