The sensitivity of an operational CO<sub>2</sub>-responsive land surface model (the ISBA-A-gs model of Météo-France) to the atmospheric CO<sub>2</sub> concentration, (CO<sub>2</sub>), is investigated for 3 vegetation types (winter wheat, irrigated maize, coniferous forest). Past (1960) and future (2050) scenarios of (CO<sub>2</sub>) corresponding to 320 ppm and 550 ppm, respectively, are explored. The sensitivity study is performed for 4 annual cycles presenting contrasting conditions of precipitation regime and air temperature, based on continuous measurements performed on the SMOSREX site near Toulouse, in southwestern France. A significant CO<sub>2</sub>-driven reduction of canopy conductance is simulated for the irrigated maize and the coniferous forest. The reduction is particularly large for maize, from 2000 to 2050 (−18%), and triggers a drop in optimum irrigation (−30 mm y<sup>−1</sup>). In the case of wheat, the response is more complex, with an equal occurrence of enhanced or reduced canopy conductance. |
