April 3–6, 2023 the A.N. Severtsov Institute of Ecology and Evolution RAS hosted a meeting of the Working Group on data processing to assess ecosystem flows of greenhouse gases in the framework of the most Important innovative project of national importance Scientific and Educational Center "Carbon in Ecosystems: Monitoring".
The meeting was attended by more than twenty researchers working at environmental and climatic stations (method of turbulent pulsations, or MTP) of the Russian RuFlux network, as well as young employees who plan to process MTP data. The attendees were addressed by Ph.D. Yulia Kurbatova, Head of the V.N. Sukachev Laboratory of Biogeocenology at IEE RAS. On the first day, four reviews and methodological reports were presented. Ph.D. Sergey Kivalov (Institute of Physical, Chemical and Biological Problems of Soil Science, Russian Academy of Sciences, Pushchino) spoke to the audience about the organization of the European network for carbon exchange measurements ICOS, as well as about the corrections used in the ICC. Arseniy Artamonov (AM Obukhov Institute of Atmospheric Physics, Russian Academy of Sciences) described the features of data processing of multilevel turbulent measurements. Ph.D. Andrey Sogachev (IEE) presented the concept and features of footprint models. Reports were also made on the features of data and their processing at different RuFlux stations: in the Krasnoyarsk Territory (PhD Vyacheslav Zyryanov, V.N. Sukachev Institute of Forestry, Siberian Branch of the Russian Academy of Sciences, Krasnoyarsk), Novgorod region (Arseny Shilkin, Research and Production Association “Typhoon”, Kaluga region, Obninsk; Center for Problems of Ecology and Forest Productivity of the Russian Academy of Sciences), Tver region (Ph.D. Vadim Mamkin and Ph.D. Olga Kuricheva , IEE), Khanty-Mansi Autonomous Region and Tomsk Region (Ph.D. Egor Dyukarev, Institute for Monitoring Climatic and Ecological Systems SB RAS, Tomsk).
On the second day, a workshop was held on processing primary data, reports were made on filling gaps in streams using reanalysis data and on determining the turbulence threshold for screening out data of inadequate quality. Messages and discussions concerned the issues of standardization of data collection, organization of data flow. Vitaly Avilov (IEE RAS) moderated the discussion on creating a common data infrastructure in the RuFlux network. On the third day, a report was made on the features of methane fluxes in ecosystems (Ph.D. Gennady Suvorov, IEE RAS), as well as a discussion of the results of an experiment on the simultaneous calculation of the same primary data by different researchers.
The meeting of the Working Group made it possible to carry out a successful exchange of experience in data processing, contributed to the strengthening of scientific ties between teams and immersion of young scientists in the fascinating world of research into the interaction of ecosystems and the atmosphere. We hope that such meetings will become regular and will involve an increasing number of teams from environmental and climate stations.
The meeting was organized by the staff of the V.N. Sukachev Laboratory of Biogeocenology and the Youth Laboratory of Environmental and Climate Research IEE RAS.
