LMDz grid LMDZ/std

LMDz grid LMDZ/std#

Description#

This plugin reads LMDz 3D domain

Two files are required to specify the LMDz domain with the LMDZ grid plugin:

  • a grid text file containing the horizontal grid coordinates

  • a ‘vcoord’ NetCDF file

YAML arguments#

The following arguments are used to configure the plugin. pyCIF will return an exception at the initialization if mandatory arguments are not specified, or if any argument does not fit accepted values or type:

Mandatory arguments#

filegrid : str, mandatory

File with longitudes and latitudes

file_vcoord : str, mandatory

File with vertical coordinates. Should be a restart file from a previous online simulation

dir_vcoord : str, mandatory

Directory where to find file_vcoord
