This library provides a Python API for accessing open Global Meteor Network (GMN) meteor trajectory data. Global meteor data is generated using a network of low-light cameras pointed towards the night sky. Meteor properties (radiants, orbits, magnitudes and masses) are produced by the GMN and are available through this library.

  • Listing available daily and monthly meteor trajectory files from the GMN Data Directory.

  • Downloading specific meteor trajectory data from the GMN Data Directory or GMN REST API.

  • Functions for loading meteor trajectory data into Pandas DataFrames.

  • Functions for retrieving available IAU registered meteor showers.


  • Python 3.8, 3.9, or 3.10


You can install gmn-python-api via pip from PyPI:

pip install gmn-python-api

Or install the latest development code, through TestPyPI or directly from GitHub via pip:

pip install -i --extra-index-url gmn-python-api==<version>


pip install git+

Refer to the Troubleshooting guide if you encounter any issues.


Simple meteor analysis example:

from gmn_python_api import data_directory as dd
from gmn_python_api import meteor_trajectory_reader

# Analyse recorded meteor data for the 24th of July 2019
traj_file_content = dd.get_daily_file_content_by_date("2019-07-24")

# Read data as a Pandas DataFrame
traj_df = meteor_trajectory_reader.read_data(traj_file_content)

print(f"{traj_df['Vgeo (km/s)'].max()} km/s was the fastest geostationary velocity")
# Output: 65.38499 km/s was the fastest geostationary velocity

print(f"{traj_df.loc[traj_df['IAU (code)'] == 'PER'].shape[0]} Perseid meteors")
# Output: 3 Perseid meteors

print(f"Station #{traj_df['Num (stat)'].mode().values[0]} recorded the most meteors")
# Output: Station #2 recorded the most meteors
