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 3-12) is from free running model, commit e9f81f49, while
ModII (years 6-7) is from nudged simulations, now only UVPS (in metdata.F90!), with main code from
commit 69f34ee + updated look-up tables and associated model code (not yet committed)
allowing for more added internally mixed condensate, coagulate and cloud processed mass
ModI PD: CAM5-Oslo, 2000 emissions, 2 years spin-up
ModI PI: CAM5-Oslo, 1850 emissions, 2 years spin-up
ModII PD: CAM5-Oslo, 2000 emissions, 5 years spin-up, nudged to CAM5 model meteorology
ModII PI: CAM5-Oslo, 1850 emissions, 5 years spin-up, nudged to CAM5 model meteorology
Known bugs/shortcomings:
* OM/OC ratio is 1.4 always, should be 2.6 for biomass burning
* Condensation/coagulation sink is function of dry size
