Fluxes crossing boundaries

NorESM can simulate several biogeochemical cycles. Here is a list of the fluxes which cross boundaries in the models and how to enable/disable interactions

Dust

CLM

CAM

kg/m2/s

Always calculated by CLM. Picked up and used by atmophere. Used differently in different aerosol-packages (bulk-aero,MAM, OSLO_AERO)

Dust

CAM

HAMMOC

kg/m2/s

Leaves CAM as cam_out%dstwet{n} ,cam_out%dstdry{n}(n=1-4), picked up by HAMMOC in coupler

DMS

HAMMOC

CAM

kg/m2/s

HAMMOC writes DMS to the coupler if one sets “CCSM_BGC=CO2_DMSA” in env_run.xml. Picked up and used by CAM-Oslo if namelist-variable dms_source==’ocean_flux’. Only compsets with MICOM%ECO run HAMMOC

kg/m2/s

Calculated by MEGAN in CLM by setting “‘isoprene = isoprene’, ‘monoterp = myrcene + sabinene +limonene + carene_3 + ocimene_t_b + pinene_b + pinene_a’” Note that any additional emission-file for monoterpenes will by ADDED to the MEGAN emissions
