Interpolated Climatology -- CBIOMES-global (alpha version) -- surface variables

**CBIOMES-global (alpha version):** 

CBIOMES-global (alpha version) is a global ocean state estimate that covers the period from 1992 to 2011. It is based on Forget et al 2015 for ocean physics [MIT general circulation model](https://mitgcm.readthedocs.io/en/latest/index.html) and on Dutkiewicz et al 2015 for marine biogeochemistry and ecosystems [Darwin Project model](https://darwin3.readthedocs.io/en/latest/phys_pkgs/darwin.html).
