Airborne observations of atmospheric composition and physical parameters

The datasets belong to the data collection "AIRMETH_vertical_profiles_Polar5". The data were collected in the Mackenzie Delta, Canada, and the North Slope of Alaska during two aircraft AIRMETH (Airborne Measurements of Methane Fluxes) campaigns (Kohnert et al., 2014, Hartmann et al., 2018, Kohnert et al., 2018, Serafimovich et al., 2018, Kohnert et al., 2018) that aimed at capturing exchange processes between the surface and the atmosphere across large arctic permafrost landscapes. The study periods were 28 June to 10 July 2012 and 19 July to 26 July 2013. The datasets included in “AIRMETH_vertical_profiles_Polar5” contain vertical profiles of parameters until the top of the atmospheric boundary layer. The data from the Mackenzie Delta were collected in 2012 and 2013, those of the North Slope of Alaska in 2012.
