Each modeling group must provide their output in the standard format (analagous to that used for OCMIP-2 and OCMIP-3). Model output that does not follow these formatting conventions cannot be included for analysis during OCMIP-4. Model groups must use the two standard routines that we have developed specifically for writing output in standard form for OCMIP-4.
Examples of calling these two output subroutines are provided in the two test programs below:
Shortly, another set of example programs will be provided to illustrate how to read a variable in from one or more non-standard netCDF files and then pass it on to the write subroutines above, in order to produce standard output files.
You will also need to transfer the OCMIP-2 routines:
The output routines can be transferred to your machine by clicking on the links above, while holding down the Shift key.
For consistency, it is crucial that all groups use the following i) short names, ii) long names, and iii) units when calling the standard output routines. If you have other variables that are not included in the list below, please notify Laurent Bopp and James Orr so that we can add them to the list below.

For instance, the short name of surface DIC is SDIC.
