Model version I (left) vs. Model version II (right)
Presenting annual means from the following simulations:
ModI & PD simulation info (CAM4-Oslo revision I: 2000 emissions, AEROCOMCTRL)
ModI & PI simulation info (CAM4-Oslo revision I: 1850 emissions, AEROCOMCTRL)
ModII & PD simulation info (CAM6-Oslo revision II: 2000 emissions, 1 years spin-up, 4 years avg nudged to ERA model meteorology)
ModI & PI simulation info (CAM6-Oslo revision II: 1850 emissions, 1 years spin-up, 4 years avg nudged to ERA model meteorology)
