To know regional-to-continental scale CO2
fluxes between atmosphere and terrestrial biosphere using an inverse model, the
CO2 measurements on plural
towers
situated in a thousand square kilometer area of West Siberia have
been carried
out since 2002. The CO2 concentrations at 80m of the tower during
daytime afternoon well represents those of PBL with its difference in ±3 ppm,
and 90% of them in ±2 ppm, in clear sky day, when no strong inversion is
occurred in winter. The tower observation expands to five sites to date, and additional
four sites will be established in a year.
