Attributes¶

data_source: str or xarray.Dataset

The y coordinate name in the data

h_coord: str

The height coordinate name in the data

pre_load: bool

Flag for loading all data into memory during initialization

weight_ncvar: str

Name of the weight data variable in the nc file(s)

bounds_error: bool

Flag for raising errors if bounds are exceeded

fill_value: number

Fill value in case of exceeding bounds, if no bounds error
