COVID-19 Dataset

During the pandemic, we have began to publish a much requested research dataset for all flights that we have tracked since 2019. You can find more information here and the dataset here.

Relatedly, you can check out the Bank of England using OpenSky data to nowcast economic indicators in the COVID-19 crisis.

Please note that the publication of this dataset ceased with the end of the year 2022.

About the OpenSky Network

The OpenSky Network is a non-profit community-based receiver network which has been continuously collecting air traffic surveillance data since 2013. Unlike other networks, OpenSky keeps the complete unfiltered raw data and makes it accessible to academic and institutional researchers. With over 30 trillion ADS-B, Mode S, TCAS and FLARM messages collected from more than 5000 sensors around the world, the OpenSky Network exhibits the largest air traffic surveillance dataset of its kind. The mission of our non-profit association is to support open global air traffic research by universities and other not-for-profit institutions. You can find more information on our blog!
