Simulating cross-polar pollution transport during POLARCAT-GRACE
International audience The POLARCAT-GRACE campaign was targeted at aircraft and satellite-remote sensing observations of biomass burning emission transport into the Arctic. During two episodes (2-5 July and 7-10 July) extended smoke plumes originating from large Siberian forest fires were advected d...
