Processing Notes : This table includes the 2-D variables listed in the "Amon" spreadsheet, omitting, however, the daily maximum and minimum temperatures. All variables should be reported as synoptic fields, not daily means.

Provenance Note :

Frequency of Time Steps to be Archived : subhrPt

Row index of entry in source sheet : 1057

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.)
