polaris.mpas.cell_mask_to_edge_mask

polaris.mpas.cell_mask_to_edge_mask(ds_mesh, cell_mask)[source]

Convert a cell mask to edge mask using mesh connectivity information

True corresponds to valid cells and False are invalid cells

Parameters:

ds_mesh (xarray.Dataset) – The MPAS mesh
cell_mask (xarray.DataArray) – The cell mask we want to convert to an edge mask

Returns:

edge_mask (xarray.DataArray) – The edge mask corresponding to the input cell mask
