Objetivo The principal goal of ESCOBA is to investigate, quantify, model and eventually predict the behavior of the global carbon cycle in response to perturbations by man and with respect to its interaction with the physical climate system on time scales of up to several hundred years. ESCOBA-Atmosphere will monitor and assess the information contained in atmospheric measurements of CO2 and other tracers linked to the global carbon cycle, and synthesise the combined knowledge on the carbon cycle into comprehensive global prognostic models, to validate these models and to perform scenario calculations. A monitoring programme of the atmospheric concentration of CO2 and its stable (13C/12C and 18O/16O in CO2) and radioactive (14C/C) isotope ratios is conducted, which is focussed on the North Atlantic, the European continent and on the Tropical Indian Ocean, which represent critical gaps in the currently operating global monitoring networks. These measurements are supplemented by observations of SF6, in order to provide a diagnostic tool to validate the atmospheric transport models used in the project. Furthermore, a new capability of measuring the oxygen to nitrogen ratio of atmospheric air using high-precision mass spectrometry is developed, which, in conjunction with atmospheric CO2 concentration observations, will permit a direct quantification of the relative contributions of terrestrial biospheric and oceanic CO2 source processes on regional and global scales. A series of model simulation studies will be conducted, comprising inversion studies with atmospheric transport models in order to establish constraints on magnitude and location of surface sources and sinks of atmospheric CO2 from atmospheric observations. Simulations of surface fluxes generated by prognostic, high-resolution models of the terrestrial and oceanic carbon reservoirs will be validated. Finally a series of scenario calculations of the future atmospheric CO2 concentration will be carried out based on scenarios of future energy and landuse using coupled comprehensive models of the global carbon cycle as developed and validated within ESCOBA.
