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)

ModII has increased sea salt emissions and also changed z0 to use the value from ERA to avoid noise


Known bugs/shortcomings:



Emissions

Zonally averaged mass mixing ratios

Zonally averaged mode parameters

Burdens

Effective dry aerosol radii

Particular Matter (PM) concentrations (CAM5-Oslo vs. CAM5-Oslo only)

Wet to total deposition ratios

Lifetimes

RH and cloud properties

Cloud droplet properties

Angstrom coefficient, aerosol optical depth, SSA and G

Aerosol optical depth for each species

Mass extinction coefficients for each species

Anthropogenic (PD - PI) aerosol and cloud fields

Radiative forcings at top of the atmosphere

Radiative fluxes at top of the atmosphere
