New method for monitoring human carbon dioxide emissions from space

A research article published in the Frontiers in Remote Sensing journal presents a method for calculating local carbon dioxide and nitrogen oxide emissions. The method can be utilised in analysing the data of the CO2M satellites scheduled to be launched in 2025.

The study developed a new method to calculate carbon dioxide (CO₂) and nitrogen oxide (NOₓ) emissions from cities and power plants. The method is based on calculating the divergence, and it utilises satellite observations from over a long period of time, such as one year.

The study was conducted in collaboration with the Finnish Meteorological Institute and the Swiss Empa institute. The CoCO2 project from the EU’s H2020 programme, the DACES project funded by the European Space Agency ESA and the Academy of Finland’s CitySpot, Atmosphere and Climate Competence Center ACCC and Centre of Excellence of Inverse Modelling and Imaging have participated in its funding.
