cobarton ceda-cc and cfcheck report for NAVGEM v20230526

[mollymacrae]

The following errors were picked up by the ceda-cc and cf checks for the free s20180125 experiment v20230526 data:

[mollymacrae]

For all files the following errors were raised:

• filename error: underscore between - should be replaced with a hyphen (e.g. change 'hus_6hrPt_NAVGEMfrees20180125_r1i1p1f1_gn_20180125-20180311.nc' to 'hus_6hrPt_NAVGEMfrees20180125-r1i1p1f1_gn_20180125-20180311.nc')

• missing required global attribute 'tracking_id' : [global_ncattribute_present]: FAILED:: Required global attributes missing: ['tracking_id']

• incorrect value for global attribute 'mip_era' : this should be changed from 'CMIP6' to 'SNAPSI' to be consistent with the MIP tables

cell methods attribute The variable attribute 'cell_methods' needs to be changed to the following for:

hus, ps, psl, rlut, tas, uas, vas: cell_methods="area: mean time: point" (currently "time: point")

pr, prc: cell_methods="area: mean time: mean" (currently "time: mean")

tntmp, tntnd, tntrl, tntrs, utendmp, utendnd, utendnogw, utendogw, vtendnogw, vtendogw: cell_methods="longitude: mean time: mean" (currently "time: mean")

va: cell_methods="longitude: mean time: point" (currently "time: point")

tasmax: cell_methods="area: mean time: maximum" (currently "time: mean")

tasmin: cell_methods="area: mean time: minimum" (currently "time: mean")

[mollymacrae]

long_name attribute

tasmax: Variable attribute long_name needs to be changed to long_name="6 hourly Maximum Near-Surface Air Temperature" (currently "6-hourly Maximum Near-Surface Air Temperature")

tasmin: Variable attribute long_name needs to be changed to long_name="6 hourly Minimum Near-Surface Air Temperature" (currently "6-hourly Minimum Near-Surface Air Temperature")

wap Variable attribute long_name needs to be changed to long_name="Omega (=dp/dt)" (currently "Omega (vertical pressure velocity)")

[mollymacrae]

hus units Variable hus units attribute should be changed to units="1" to be consistent with the MIP tables (currently "kg kg-1")

[mollymacrae]

cf checks

Running cf checks raised a couple of additional errors:

For variables: pr,prc,tasmax,tasmin,tntmp,tntnd, tntrl, tntrs, untendmp, utendnd, utendnogw, utendogw, vtendnogw, vtendogw

• when checking time_bnds variable: 'ERROR: (4.4.1): Attribute calendar may only be attached to time coordinate variable'
• when checking nbnd varible: 'ERROR: (5): co-ordinate variable not monotonic'

For variables: tntnd, utendnd, utendmp

• when checking variable: 'ERROR: (3.3): Invalid standard_name' This error can be ignored as these are consistent with the standard_name in the MIP tables.
