• For C3S, values (1x1deg grid) prescribed:
  center of 1-degree cells
  dimension lat=180

      [-89.5, -88.5 , ..., -0.5, 0.5 ... 89.5]

• For C3S, values (1x1deg grid) prescribed: prescribed:
  center of 1-degree cells
  dimension lon=360

     [0.5 , 1.5 , ..., 358.5, 359.5]

Pa

• For C3S, values prescribed:
  dimension plev=12

      [1000., 925., 850., 700., 500., 400., 300.,          200., 100., 50., 30., 10.]

• Values here are written in hPa, they should be Pa.
• This is also referred to as isobaric level by some tools

depth

(for soil levels)

None

(scalar auxiliary coordinate for ocean variablevariables)s

m

• For C3S, when used for ocean temp/salinity in the upper 300m, values prescribed:

      depth=300; depth_bnds=[0,300]

• Only used for soil model levels and ocean variables. 
• Number and depth of levels are not prescribed by C3SWhen used for ocean variables it's scalar auxiliary coordinates and its dimension is "None"

CMIP5:

2mtemp: 1.

10mu/v: 1.

CMIP5:

2mtemp: 10.

10mu/v: 30.

• Used for single level fields (height, soil,SST)

       e.g. ~2 m standard surface air temperature and surface humidity height or ~10 m standard wind speed height

None

(scalar auxiliary coordinate)

• Used for mixed layer depth

None

(scalar auxiliary coordinate)

degC

CF: canonical units are K

• Used for isotherm depths
