Abstract

The evaluation of the previously developed one-dimensional model of radiocarbon atmospheric transport in vegetated canopies against C-14 concentration data collected at the site of SMEAR-II research station was presented. In most cases, the simulated vertical profiles of C-14 concentrations within the canopy layer agreed reasonably with measurements, the correlation coefficient of simulated vs. observed concentrations was 0.72. The developed model could be used to evaluate vertical variations of C-14 concentrations in vegetated canopy layers.
