Atmosf\u00e6ren er det, vi ind\u00e5nder, og udg\u00f8r en vigtig del af Jordens klimasystemer, s\u00e5 det er vigtigt at vide mere om den. Sentinel-5P er specialiseret i at opspore forurening i atmosf\u00e6ren.

Ved hj\u00e6lp af Tropomi kan Sentinel-5P kortl\u00e6gge forurenende stoffer i luften over hele verden. N\u00e5r vi f\u00f8rst kender omfanget af forureningsproblemet, vil vi v\u00e6re bedre i stand til at finde l\u00f8sninger, der kan holde vores luft ren.<\/p>\n<p>Stefan Dech er direkt\u00f8r for Jordobservationscentret ved det tyske rumfartscenter (DLR).

Satellittens Tropomi-instrument lovede at levere billeder af forurenende stoffer i h\u00f8jere opl\u00f8sning end nogensinde f\u00f8r, og det lever bestemt op til sit l\u00f8fte.\u201c<\/p>\n<p>Hvordan tror du, luftkvaliteten er der, hvor du bor?
