V.E. Zuev Institute of Atmospheric Optics is now undertaking an extensive research aircraft campaign aimed to document chemical composition of the air shed above the Russian Arctic regions. The campaign has been started at the beginning of September, 2020. During 1st and 2nd of September, two test flights were performed in the vicinity of Novosibirsk (Russia) to check new instrumentation installed on board the OPTIK Tu-134 aircraft laboratory (Fig. 1).

The equipment of the aircraft allows in-situ measurements of aerosol properties and concentrations of such trace gas species as CO2, CH4, CO, O3, NO/NO2/NOX, SO2 to be carried out. Onboard airborne lidar enables to study and derive vertical profiling of aerosols, as well as organic matter content in the sea water layer (with a depth up to 25 m).

The main phase of the campaign began on 4th September by the flight from Novosibirsk to Arkhangelsk. The weather in the Russian Arctic is unusually warm for this period of the year (i.e. above +5°C even at nighttime). After arriving in Arkhangelsk, we faced some pandemic and logistic problems those were overcome. Finally, we arrived in Anadyr, where we are now waiting for favorable weather conditions to continue the flight campaign.

This campaign is funded by the Ministry of Science and Higher Education of the Russian Federation (State Contract No 05.619.21.0012).

We would like to acknowledge our colleagues from the following organizations provided the Letters of Support enabled our research campaign to be undertaken, and in particular, Laboratoire des sciences du climat et de l’environnement and Laboratoire atmosphères, milieux, observations spatiales (France); Finnish Meteorological Institute and Institute for Atmospheric and Earth System Research, University of Helsinki (Finland); Center for Global Environmental Research at the National Institute for Environmental Studies (Japan); the National Oceanic and Atmospheric Administration, US Department of Commerce (USA); Max-Planck-Institute for Biochemistry (Germany); and University of Reading (UK).
