Sources of polluting ammonia emission identified from space - Earth short science news

Scientists have prepared the first world map of atmospheric ammonia by analyzing satellite measurements between 2008-2016. The map shows 241 point sources of ammonia emissions due to human activities like intensive animal farming and industry.

The study furthers reveals that previous estimations about atmospheric ammonia concentrations were far too low.

Improved management of ammonia pollution is thus required to prevent the degradation of the quality of the air we breathe.
