Extended use

Extending CAMMAC use beyond CMIP6

CAMMAC is yet validated only with data for project CMIP6, and this project name is implicit in some functions. However, a former version of CAMMAC was used to process CMIP5 data, and restoring this possibility could be considered. For other projects, with a less strict output data organization, an analysis would be necessary for assessing CAMMAC hard needs for processsing it. It would also be advisable to test the derived_variable parameters for reaching data in other projects

Using CAMMAC outside the ESPRI platform

CAMMAC was developped on the ESPRI platform. Because CliMAF has a built-in knowledge of CMIP6 data organization on that platform (and a few others), this allows to avoid describing this data oragnization in CAMMAC. For using CAMMAC on other platforms with CMIP6 data, two cases arise :

• if the data is organized according to CMIP6 Data Reference Syntax, i.e. with that kind of file structure

  <some root>/
    <mip_era>/
      <activity_id>/
        <institution_id>/
          <source_id>/
            <experiment_id>/
              <member_id>/
                <table_id>/
                  <variable_id>/
                    <grid_label>/
                      <version>/
                        <variable_id>_<table_id>_<source_id>_<experiment_id >_<member_id>_<grid_label>[_<time_range>].nc
  

  the only need is to declare the CMIP6 data root directory to CliMAF, by :

  >>> cdef('root','/my/CMIP6/data_root',project="CMIP6")
  

• otherwise, one has to duplicate the declaration of climaf module climaf.project.cmip6 with the needed changes regarding base_patterns (toward the end of the module).

• for using the data inspection notebook (see Notebooks for data registering, control and pre-processing), a slight change is necessary to adapt to local data organization (see there).
