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.

stid¶

The ID of the radar station

Type: str

dt¶

The date and time of the data

Type: Datetime instance

vol_hdr¶

The unpacked volume header

Type: namedtuple

sweeps¶

Data for each of the sweeps found in the file

Type: list of tuples

rda_status¶

Unpacked RDA status information, if found

Type: namedtuple, optional

maintenance_data¶

Unpacked maintenance data information, if found

Type: 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: namedtuple, optional

clutter_filter_bypass_map¶

Unpacked clutter filter bypass map, if present

Type: dict, optional

rda¶

Unpacked RDA adaptation data, if present

Type: dict, 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.

Create instance of Level2File.

Parameters: filename (str or file-like object) – If str, the name of the file to be opened. Gzip-ed files are recognized with the extension ‘.gz’, as are bzip2-ed files with the extension bz2 If filename is a file-like object, this will be read from directly.
