- pyart.io.read_rsl(filename, field_names=None, additional_metadata=None, file_field_names=False, exclude_fields=None, delay_field_loading=False, include_fields=None, radar_format=None, callid=None, skip_range_check=False)[source]¶
Read a file supported by RSL.
filename (str or RSL_radar) – Name of file whose format is supported by RSL.
field_names (dict, optional) – Dictionary mapping RSL data type names to radar field names. If a data type found in the file does not appear in this dictionary or has a value of None it will not be placed in the radar.fields dictionary. A value of None, the default, will use the mapping defined in the Py-ART configuration file.
additional_metadata (dict of dicts, optional) – Dictionary of dictionaries to retrieve metadata from during this read. This metadata is not used during any successive file reads unless explicitly included. A value of None, the default, will not introduct any addition metadata and the file specific or default metadata as specified by the Py-ART configuration file will be used.
file_field_names (bool, optional) – True to use the RSL data type names for the field names. If this case the field_names parameter is ignored. The field dictionary will likely only have a ‘data’ key, unless the fields are defined in additional_metadata.
exclude_fields (list or None, optional) – List of fields to exclude from the radar object. This is applied after the file_field_names and field_names parameters. Set to None to include all fields specified by include_fields.
include_fields (list or None, optional) – List of fields to include from the radar object. This is applied after the file_field_names and field_names parameters. Set to None to include all fields not specified by exclude_fields.
delay_field_loading (bool) – True to delay loading of field data from the file until the ‘data’ key in a particular field dictionary is accessed. In this case the field attribute of the returned Radar object will contain LazyLoadDict objects not dict objects.
radar_format (str or None) – Format of the radar file. Must be ‘wsr88d’ or None.
callid (str or None) – Four letter NEXRAD radar Call ID, only used when radar_format is ‘wsr88d’.
skip_range_check (bool, optional) – True to skip check for uniform range bin location, the reported range locations will only be verified true for the first ray. False will perform the check and raise a IOError when the locations of the gates change between rays.
radar (Radar) – Radar object.
