Modeling Realm : atmos

CMOR Directive Positive :

Section of a table : Amon_2d

The MIP table : Amon

Provenance : Amon ((isd.003))

Processing Notes : Report from all simulations (both emission-driven and concentration-driven) performed by models with fully interactive and responsive carbon cycles.

Provenance Note : Amon_2d

Frequency of Time Steps to be Archived : mon

Row index of entry in source sheet : 57

Description : This is what the atmosphere sees (on its own grid). This field should be equivalent to the combined natural fluxes of carbon (requested in the L_mon and O_mon tables) that account for natural exchanges between the atmosphere and land or ocean reservoirs (i.e., "net ecosystem biospheric productivity", for land, and "air to sea CO2 flux", for ocean.)
