isimpson002 cf checks report for CESM2-CAM6 v20230225

[mollymacrae]

The following errors were raised by the cf checks. Some may ignored if the metadata is consistent with the SNAPSI mip tables.

[mollymacrae]

missing variable zlon_bnds
for variables epfy, epfz, utendepfd, utendmp, utendogw, utendvtem, utendwtem, vtem, vtendogw, wtem:
missing variable 'zlon_bnds'
referenced in variable zlon with attribute 'zlon:bounds = "zlon_bnds"':

ERROR: (7.1): bounds attribute referencing non-existent variable zlon_bnds

[mollymacrae]

missing variable time_bnds
for variables ps, psl, rlut,siconca, snd, snw, ta, tas, tos, ua, va, wap, zg:
missing variable 'time_bnds'
referenced in variable time with attribute 'time:bounds = "time_bnds"'

ERROR: (7.1): bounds attribute referencing non-existent variable time_bnds

[mollymacrae]

incorrectly labelled time_bnds
for variables mrso, mrsos:
time has attribute 'time:bounds = "time_bounds"' but variable is called "time_bnds" not "time_bounds"

ERROR: (7.1): bounds attribute referencing non-existent variable time_bounds

Errors raised by cfchecks where the metadata is consistent with the snapsi tables:

attribute valid_min and valid_max error:
Where valid_min or valid_max are specified, they are in string format (e.g. lat:valid_max = "90.0"). This is consistent with the snapsi tables, but raises a cf error which expects a numerical value:

ERROR: Attribute valid_min of incorrect type (expecting 'Numeric' type, got 'String' type)

• error ignored as metadata consistent with snapsi mip table
  error also found in dspecq cf checks report for CNRM-CM61 v20230215 #35

invalid value for positive attribute
error raised by cfcheck but consistent with snapsi tables:
ERROR: (4.3): Invalid value for positive attribute
E.g. variable clt has attribute 'clt:positive = "" ;'

• error ignored as metadata consistent with snapsi mip table

climatology attribute error
Climatology attribute of plev coordinate not recognised by cfchecks but consistent with snapsi tables (e.g. plev:climatology = "")
ERROR: (7.4): Climatology attribute referencing non-existent variable
ERROR: (4.4.1): Attribute climatology may only be attached to time coordinate variable

• error ignored as metadata consistent with snapsi mip table

cell_measures variable error:
ERROR: (7.2): cell_measures variable areacella must either exist in this netCDF file or be named by the external_variables attribute

• error ignored as raised here
