Atmospheric and Ocean Optics: Atmospheric Physics

The continuous ground-based measurements of greenhouse gases carried out in Siberia in the past two decades allowed the long-term trends, as well as the diurnal and seasonal cycles of CO2 and CH4 to be derived for this poorly studied region (Belikov et al., 2019). To date, these in-situ observations are made at the joint Japan-Russia Siberian Tall Tower Inland Observation Network (JR-STATION) consisted of 6 automated stations that should be maintained several times per year. In late October to early November 2018, we have undertaken the first mobile campaign to derive a distribution of CO2 and CH4 concentrations at high spatial resolution while traveling to the sites of the above network. For that, we used a commercially available GHG CRDS analyzer (G4301, Picarro Inc., Santa Clara, CA, USA) installed in an off-road vehicle (Arshinov et al., 2019). Over one trip, the instrument were driven over 7000 km throughout the study area.In March, June, August, and October 2019 we have performed four more campaigns along the same route. This enabled the seasonal pattern of CO2 and CH4 concentrations to be obtained over a huge area of West Siberia between 54.5&#176; and 63.2&#176; north latitude and between 62.3&#176; and 85.0&#176; east longitude, as well as to reveal a large- and small-scale spatial heterogeneity in CH4 mixing ratios particularly over wetland regions. We plan to continue mobile campaigns to cover interannual variations.&#160;This work was supported by the Ministry of Science and Higher Education of the Russian Federation under State Contract No. 14.616.21.0104 (ID No RFMEFI61618X0104).Belikov, D.; Arshinov, M.; Belan, B.; Davydov, D.; Fofonov, A.; Sasakawa, M.; Machida, T.

Abstract This is the introductory article for the special issue of Izvestia, Atmospheric and Oceanic Physics dedicated to the 2019 Lomonosov Gold Medal of the Russian Academy of Sciences awarded to Academician Georgy Golitsyn “for making an outstanding contribution to the study of atmospheric physics of the Earth and planets and the development of the theory of climate and its changes” and to foreign member of the Russian Academy of Sciences Professor Paul Joseph Crutzen “for making an outstanding contribution to the chemistry of the atmosphere and assessing the role and biogeochemical cycles in climate formation.” This issue includes an article highlighting the contributions Golitsyn and Crutzen made to the study of physics and chemistry of the atmosphere, climate, and biogeochemical cycles, as well as articles written for this special issue with the participation or recommendation of the laureates.
