Comparing atmospheric transport models for future regional inversions over Europe – Part 1: mapping the atmospheric CO2 signals
The CO2 source and sink distribution across Europe can be estimated in principle through inverse methods by combining CO2 observations and atmospheric transport models. Uncertainties of such estimates are mainly due to insufficient spatio-temporal coverage of CO2 observations and biases of the models. In order to assess the biases related to the use of different […]
