Detection of wildfire pollution in the Arctic using a network of FTIR spectrometers and GEOS-Chem
Ground-based FTIR instruments provide simultaneous measurements of CO, HCN and C2H6 at high-latitudes. Detection of CO enhancements and strong correlations with HCN and C2H6 are indicative of wildfire pollution events. The GEOS-Chem tagged CO simulation provides attribution of CO sources to FTIR mea...

Summary: | Ground-based FTIR instruments provide simultaneous measurements of CO, HCN and C2H6 at high-latitudes. Detection of CO enhancements and strong correlations with HCN and C2H6 are indicative of wildfire pollution events. The GEOS-Chem tagged CO simulation provides attribution of CO sources to FTIR measurements from 2003-2017. At all FTIR sites, wildfire pollution events are detected annually and attributed to Boreal wildfires in North America and Asia. |
