GENERAL INFORMATION
Title of Data set: Atmospheric mixing ratios of CO2 and CH4 at Ambarchik, NE Siberia, 2014-2017 Description: Ambarchik is located at the mouth of the Kolyma River, which opens to the East Siberian Sea (69.62N, 162.30E). The majority of the landscape in the immediate vicinity of the locality is wet tussock tundra. At the ecoregion scale, Ambarchik is bordered by Northeast Siberian Coastal Tundra ecoregion in the west, the Chukchi Peninsula Tundra ecoregion in the east, and the Northeast Siberian Taiga ecoregion in the south. Major components contributing to the net carbon exchange processes in the area are tundra landscapes including wetlands and lakes, as well as the Kolyma River and the East Siberian Arctic Shelf. Ambarchik hosts a weather station operated by the Russian meteorological service, whose staff is the entire permanent population of the locality. The closest town is Chersky (∼ 100 km to the south, with a population of 2857 as of 2010), with no other larger permanent settlement closer than 240 km. Thus, the site does not have any major sources of anthropogenic greenhouse gas emissions in the nearby. The only regular anthropogenic CO2 and potential CH4 sources that may influence the measurements are from the facility itseöf, including the building that hosts the power generator and the inhabited building. The atmospheric carbon observation station Ambarchik began operation in August 2014. It consists of a 27 m tall tower with two air inlets and meteorological measurements, while the majority of the instrumentation is hosted in a rack inside a building. Atmospheric mole fractions of CH4 , CO2 , and H2O are measured by an analyzer based on the cavity ring-down spectroscopy (CRDS) technique (G2301, Picarro Inc.), which is calibrated against WMO-traceable reference gases at regular intervals. The tower is located 260m from the shoreline, with a base elevation of 20 m a.s.l.
