-**Ensemble runs:**          No
+**Resolution:**             f19_g16= 1.9x2.5 degree atmosphere/land. Dipolar ocean/ice grid, ~ 1 degree
-**Resolution:**             f19_g19 = 1.8x2.5
+**Emission year(s):**       1850-2005 (aerosol and aerosol-precursors)

+**Greenhouse gases:**        Prescribed concentrations 1850-2005
 **Emission inventories**    IPCC AR5, see references in [[http://www.geosci-model-dev.net/6/207/2013/gmd-6-207-2013.html|Kirkevåg et al. (2013)]]
-**Frequency for output:**   Monthly (for atm, ocn and lnd)
+**Frequency for output:**   Monthly and selected daily 1850-1949: Monthly + daily + 6h +3h as defined by CMIP5: 1950-2005
+**Active/changing forcing agents:**  Greenhouse gases: Direct and indirect (1. & 2.) effects of SO4, POM and BC.
+** Special considerations: ** An extension of the historical simulation to 2012 is done by using RCP8.5 scenario; There is a bug in the column burden for aerosols. The column burden has to be recalculated using concentrations. This was corrected before the RCP scenarios (revision 118); The CMIP 5 files for these simulations can be found at /projects/NS9034K/CMIP5/output1/NCC/NorESM1-M/historical.
-**Active/changing forcing agents:**  Direct and indirect (1. & 2.) effects by anthropogenic SO4, POM and BC. The effects of all BC is found from the difference between the experiments N_r99yr116 and N_r99noBCyr116, and the effect of BC deposited on snow and sea-ice is found from the difference between N_r99yr116 and N_r99noBCdepyr116.
