C Isotope streams for CMIP7

[wwieder]

Raw data for CO₂ Isotope data for CMIP7 are available have been dowloaded:
/glade/campaign/cesm/cesmdata/input4MIPs_raw/input4MIPs/CMIP7/C4MIP/ImperialCollege/ImperialCollege-3-0

CMIP7 data start in 1700 and include 4 sectors for 14C data, whereas CMIP6 data started in 1850 and had only 3 sectors for 14C

Sample cmip6 data are here /glade/campaign/cesm/cesmdata/inputdata/lnd/clm2/isotopes/atm_delta_C13_CMIP6_1850-2015_yearly_v2.0_c190528.nc (global values) and /glade/campaign/cesm/cesmdata/inputdata/lnd/clm2/isotopes/atm_delta_C14_CMIP6_3x1_global_1850-2015_yearly_v2.0_c190528.nc (which had 3 sector for Northern Hemisphere, Tropics, & Southern Hemisphere)

Is additional work needed to process the raw data?
I'm imagining changes will be needed to define the new sectors for 14C data?
Who has institutional knowledge about these data?

I will look into this and figure out what needs to be done.
