  1. Pollution: New ammonia emission sources detected from space

    Publishing date:

    December 6, 2018

    Researchers from the CNRS1 and the Université Libre de Bruxelles (ULB) have prepared the first global map of the distribution of atmospheric ammonia (NH3) by analyzing measurements taken by satellites between 2008 and 2016. The IASI interferometer developed by the CNES allowed them to catalog more than 200 ammonia sources, two-thirds of which had never been identified before. These sources are essentially sites of intensive livestock production and industrial activity. The team’s findings are published in Nature (December 5).

  2. IASI pinpoints 248 ammonia emission hotspots

    Publishing date:

    December 20, 2018

    By analysing measurements from the Infrared Atmospheric Sounding Interferometer (IASI), a French-Belgian team has compiled the first global map of ammonia emissions with a resolution of one kilometre. The team identified 248 hotspots, 85% of them originating from intensive livestock farming and industrial nitrogen fertilizer plants. Their results were published on 5 December 2018 in the journal Nature.
