led by the US National Center for Atmospheric Research found that emissions associated with mining operations in Africa’s Copperbelt can be quantified from space.can have a significant impact on the quality of life of the people living nearby,” said Pieternel Levelt, director of NCAR’s Atmospheric Chemistry Observations and Modeling Lab and senior author of the paper that presents the new findings.
To quantify these emissions, the research team turned to data from the TROPOspheric Monitoring Instrument onboard the European Space Agency’s Copernicus Sentinel-5 Precursor satellite . TROPOMI can monitor a number of trace gases important for air quality, including nitrogen dioxide. “We thought that these copper and cobalt mining operations could affect local air quality; we just didn’t know how much given the lack of ground monitoring in the region,” said NCAR scientist Sara Martínez-Alonso, who is the study’s lead author., as is the case in the Copperbelt. With satellite observations, we were able to quantify emissions from individual mines and put those emissions into perspective.
