Terrestrial Carbon Observing System Siberia, TCOS, includes an implementation of the first components of a continental scale observing system for an evaluation of the net Siberian carbon balance and its variation from year to year. This goal is addressed by means of an integrated top-down and bottom-up approach consisting of:
(1) Continuous surface flux measurements of CO2 in key ecosystems at 4 locations.
(2) Regular bi-weekly vertical profiles of the concentration of CO2 and other carbon cycle relevant tracers (carbon isotopes, CO, CH4, O2/N2 ratio) at 6 locations across Russia. Measurements will be made in the lower troposphere using light aircraft to a height of 3000 m.
(3) Development and implementation of a continental scale meteorological and biogeochemical-modelling framework to allow a determination of net carbon balance of the study region.
