Overview

The pyodim library provides essential functions for handling ODIM H5 radar data. It reads radar sweeps and converts them into xarray datasets, handling various metadata and radar coordinates transformations. The main function, read_odim, enables easy access to radar data in a format compatible with Python's data analysis ecosystem.

Installation

pyodim is available on PyPI:

pip install pyodim

It requires the following packages: h5py pyproj pandas numpy xarray dask.

Usage

The main entry point for pyodim is the read_odim function, which reads a sweep from an ODIM H5 file and outputs an xarray dataset.

Example

from pyodim import read_odim

# Read an ODIM H5 file
dataset = read_odim("radar_file.h5", nslice=0)
print(dataset)

read_odim takes the following parameters:

• odim_file (str): Path to the ODIM H5 file.
• nslice (int, optional): Sweep number to read (default is 0).
• include_fields (List, optional): Fields to read.
• exclude_fields (List, optional): Fields to exclude.
• check_NI (bool, optional): Check Nyquist parameter consistency (default is False).
• read_write (bool, optional): Open in read-write mode if True.
