100 ans de données météorologiques d’Environnement et Changement climatique Canada dans Commons


Open Data, Research / Science / Medicine

Type of session:



In 2019, Wikimedia Canada (WMCA) undertook an ambitious project in partnership with the Ministry of the Environment and Climate Change: importing a century's worth of weather data into Wikimedia Commons. Until now, the data had only been available upon request to the Ministry. This massive dataset was collected by more than 8,700 weather stations across Canada over a 100-year period. This is the first time that such a large dataset has been uploaded to Commons. A wide range of information has been collected: maximum and minimum temperatures, rainfall, snowfall on the ground in centimeters... More than 28 types of data total. The project has multiple goals: to make the data accessible to all, to encourage the reuse of this data in wiki templates, to offer a joint dataset for people from different organizations, and, who knows, perhaps to encourage other governments to do similar projects. This project was led by Ha-Loan Phan (Wikimedia Canada), Pierre Choffet (Wikimedia Canada), Miguel Tremblay (Environment and Climate Change Canada).
