The standard generic complete name for G5NR products appear as

c1440_NR.collection.timestamp.nc4

::'''c1440_NR.collection.timestamp.nc4'''

where

c1440_NR

'''c1440_NR '''

::the c1440 token indicates the resolution of the cubed-sphere grid. 14402 is the number of grid points in each face of the cubed-sphere. NR stands for Nature Run.

collection

'''collection'''

::The operational GEOS-5 data are organized into file collections that contain fields with common characteristics. However, computational considerations required that 3D collections have a single variable in them. Collection names are of the form

::::'''freq_dims_group_HV'''

Line 22:

::The '''tdav''F'' ''' files typically contain monthly diurnal files, meaning, monthly means for each hour of the day: 0 UTC, 1 UTC, …, 23UTC.

'''dims'''

::'''dims''': '''2d''' for collections with only 2-dimensional fields or '''3d''' for collections with a mix of 2- and 3-dimensional fields.

::'''2d''' for collections with only 2-dimensional fields or '''3d''' for collections with a mix of 2- and 3-dimensional fields.

'''group'''

::'''group''': A short mnemonic for the type of fields in the collection, or the variable name for single-variable collections.

'''HV'''

::'''HV''': Horizontal and Vertical grid, where

::Horizontal and Vertical grid, where

:::'''H''' can be:

::'''H''' can be:

::::'''N''': Nominal (full) horizontal resolution of lat/lon grid.

::::'''C''': Coarse (reduced) horizontal resolution of lat/lon grid

::'''V''' can be:

:::'''V''' can be:

::::'''x''': horizontal-only data (surface, single level, etc.); ''dims'' must be '''2D'''

::::'''p''': pressure-level data (see Appendix B of spec file TODO); ''dims'' must be '''3D'''

::::'''p''': pressure-level data (see Appendix B of spec file for levels TODO); ''dims'' must be '''3D'''

::::'''v''': model layer centers (see Appendix B of spec file TODO); ''dims'' must be '''3D'''

::::'''e''':

::::'''e''': model layer edges (see Appendix B of spec file); dims must be 3D

'''timestamp'''

::This token defines the date and time associated with the data in the file. It has the form ''yyyymmdd_hhmmz'', where

::::'''yyyy''' - year string (e.g. "2006")

::::'''mm''' - month string (e.g. "09" for September)

::::'''dd''' - day of the month string

::::'''hh''' - hour (UTC)

::::'''mm''' - minute

'''nc4''': All files are in the NetCDF-4 format, hence the suffix ".nc4".
