iconarray.backend.grid#

The grid module contains functions relating to the grid information for ICON data, such as merging ICON data with the grid data to provide one merged dataset.

Functions

`add_cell_data`(ds, grid)	Add clon, clat, clon_bnds, and clat_bnds coordinates from the grid file to the dataset.
`add_edge_data`(ds, grid)	Add elon, elat, elon_bnds, and elat_bnds and other edge related coordinates from the grid file to the dataset.
`check_cell2cell`(ds_grid)	Check consistency of the cell->cell connectivity.
`check_cell2vertex`(ds_grid)	Check consistency of the cell->vertex connectivity.
`check_grid_information`(file)	Check if grid information is available in file.
`check_vertex2cell`(ds_grid)	Check consistency of the vertex->cell connectivity.
`combine_grid_information`(file, grid_file)	Combine grid information.
`filter_by_var`(dataset, variable)	Filter dataset to single variable dataset.
`get_cell_dim_name`(ds, grid)	Get name of dimension in ICON data xarray dataset which identifies the cell dimension.
`get_edge_dim_name`(ds, grid)	Get name of dimension in ICON data xarray dataset which identifies the edge dimension.
`get_time_coord_name`(ds)	Get name of time coordinate in xarray dataset which has attribute standard_name = 'time' and datatype of datetime.
`grid_consistency_check`(ds_grid)	Perform consistency check of the grid.
`open_dataset`(file[, variable, decode_cf, ...])	Open either NETCDF or GRIB file.
`show_GRIB_shortnames`(file)	Show available shortNames of data within a GRIB file, which can be used to filter a dataset when opening a GRIB file.

Exceptions

WrongGridException(grid[, message])

Indicate wrong grid provided to be merged with ICON data.
