Model version I (left) vs. Model version II (right)
Presenting annual means from the following simulations:
Both ModI and ModII are featureCAM5-OsloDevelopment_trunk2.0-6 set up with MG1.5, CLM4.5, and online DMS/POM,
using compset NUDGEPTAEROUPD1
ModI (years 2012-2014) is from ERA nudged simulations (UVPS), commit cdaeb5e
ModII (years 2009-2010) is from ERA nudged simulations (UVPS), commit e27db49
I.e., code changes from ModI to ModII are: uodated BC properties (sizes, mass density and refractive index)
and a fix for previously missing SOA (ca 18%) in the look-up tables, which affected both aerosol optics and size
ModI PD: CAM5-Oslo, 2000 emissions, 11 years spin-up, nudged to ERA (2001-2015)
ModI PI: CAM5-Oslo, 1850 emissions, 11 years spin-up, nudged to ERA (2001-2015)
ModII PD: CAM5-Oslo, 2000 emissions, 3 years spin-up, nudged to ERA (2006-2010, shortened due to problems at Vilje)
ModII PI: CAM5-Oslo, 1850 emissions, 3 years spin-up, nudged to ERA (2006-2010, shortened due to problems at Vilje)
Known bugs/shortcomings:
* Condensation/coagulation sink is function of dry size
