Map showing the DLR-Falcon aircraft flight tracks during the ACCESS airborne campaign based in Andenes (69.29N, 16.14E), northern Norway, in July 2012. Flights focused on sampling emissions from shipping (#1, 2, 6, 9), oil/gas extraction activities (#7, 8), Kola Peninsula metal smelting (#3) and Siberian biomass burning (#4, 5). Flights #10–14 were survey flights over northern Scandinavia (see Roiger et al. 2015). Flight altitudes are indicated on the colour scale. The AMAP region (orange) and the Arctic Circle (turquoise) are also indicated. From Roiger et al. (2015). ©American Meteorological Society. Used with permission
