Publisher-reported update

2018-12-14

Measurements of the concentrations of air pollutants (Nitric oxide + Nitrogen dioxide - NOx, Sulfur dioxide - SO2, Ozone - O3 and PM2.5) were made at Resolute (2013-2017), Cape Dorset (2013-2017) and Pond Inlet (2018-), in addition to basic meteorology (wind speed and direction, temperature, humidity). The primary objective was to investigate the impact of increasing ship traffic on the air quality in northern communities, in support of Arctic Air Quality model development as well as policy work for the International Maritime Organization. A secondary objective was to evaluate the impact of community diesel power plants on the local air quality. Data consists of quality-controlled 1-minute averages, calibrated in post-processing against traceable standards. Locations: Resolute: 74° 42’ 23”N, 94° 58’ 08” W Cape Dorset: 64° 13’ 48”N, 76° 31’ 49” W Pond Inlet: 72° 41’ 53”N, 77° 58’ 23” W
