Temporal variations of atmospheric CO2 concentration and carborn isotope ratio in Ny-Alesund, Svalbard
Ground based observation of the atmospheric CO_2 concentration and its carbon isotope, δ^<13>C, have been performed in Ny-Ålesund, Svalbard since 1991. The CO_2 concentration and δ^<13>C observed in 1991-1999 showed clear seasonal cycles with peak-to-peak amplitudes of 16.5‰ ppmv and 0.8...
