Level2File#
- class metpy.io.Level2File(filename, *, has_volume_header=True)#
Handle reading the NEXRAD Level 2 data and its various messages.
This class attempts to decode every byte that is in a given data file. It supports both external compression, as well as the internal BZ2 compression that is used.
- vol_hdr#
The unpacked volume header
- rda_status#
Unpacked RDA status information, if found
- Type
collections.namedtuple
, optional
- maintenance_data#
Unpacked maintenance data information, if found
- Type
collections.namedtuple
, optional
- maintenance_data_desc#
Descriptions of maintenance data fields, if maintenance data present
- Type
dict, optional
- vcp_info#
Unpacked VCP information, if found
- Type
collections.namedtuple
, optional
- rda_adaptation_desc#
Descriptions of RDA adaptation data, if adaptation data present
- Type
dict, optional
Notes
The internal data structure that things are decoded into is still to be determined.
