sl.grid.addinfo: Add Grid Variables to CDO Grid File

In helgegoessling/spheRlab: Spherical Geometry, Analysis, and Plotting of Geoscientific Data on Arbitrary Grids

Add Grid Variables to CDO Grid File

Description

Add additional variables from a spheRlab grid list to a corresponding CDO grid file (NetCDF). SHOULD BE DEPRECATED NOW THAT sl.grid.writeCDO CAN WRITE TO NetCDF DIRECTLY.

Usage

sl.grid.addinfo(grid, ncdf.file.in, ncdf.file.out = paste0(ncdf.file.in,"_addinfo.nc"), add.cell_area = TRUE, add.node_node_links = TRUE, add.triag_nodes = TRUE, add.coast = TRUE)

Arguments

grid	a spheRlab grid list as returned by sl.grid.readFESOM.
ncdf.file.in	a character specifying the path and file name of the file to which additional grid variables shall be added.
ncdf.file.out	a character specifying the path and file name of the output file.
add.cell_area	a logical value indicating whether or not to add cell (stamp polygon) areas.
add.node_node_links	a logical value indicating whether or not to add node-node links.
add.triag_nodes	a logical value indicating whether or not to add triangular element triplets.
add.coast	a logical value indicating whether or not to add coast information.

Details

This is a special function that is typically used when converting FESOM grid information to a CDO-readable format, see the example below.
