polaris.ocean.vertical.diagnostics.geom_thickness_from_ds

polaris.ocean.vertical.diagnostics.geom_thickness_from_ds(ds, config)[source]

Extract or compute geometric layer thickness from dataset.

Parameters:

ds (xarray.Dataset) – An ocean dataset containing either ‘layerThickness’ directly, or ‘SpecVol’ and ‘PseudoThickness’ to compute it
config (polaris.config.PolarisConfigParser) – Configuration options for the test case

Returns:

layer_thickness (xarray.DataArray) – The geometric layer thickness in meters

Raises:

ValueError – If neither layerThickness nor the variables needed to compute it are present in the dataset
