OMIP-BGC boundary conditions

To make the OMIP-BGC simulations, model groups need boundary conditions for atmospheric gas concentrations of CFC-11, CFC-12, SF₆, and CO₂ as well as carbon isotope ratios (Δ¹⁴C and δ¹³C). These boundary conditions are described in Orr et al. (2017).  To download them, click on the links below.

Boundary conditions:

• For CFC-11, CFC-12, and SF6, atmospheric boundary conditions are provided by Bullister et al. (2016) as a CDIAC repository 
• Atmospheric CO2 is from the supplement of Meinshausen et al. (2017) 
  
• Atmospheric Δ14C and δ13C records are those constructed by Heather Graven for C4MIP and OMIP-BGC. Their permanent home is at input4MIPS. To find these 2 files, once on the input4MIPS page, type "OMIP" in the "Search and Download Data" box on the right, then click "Go".
