100 years of open access weather data
Enhancing, disseminating and reusing our meteorological heritage

Map of the 8,756 weather stations of the Meteorological Service of Canada that once existed.
Wikimedia Canada's ECCC project consists of importing, in Wikimedia Commons, a century of meteorological data collected by 8,756 stations across Canada. The objectives of the project include reusing our meteorological heritage, influencing the rest of the world to import similar data in open access in Wikimedia Commons, and solving some of the climate change issues that affect us.


In 2019, Environment and Climate Change Canada (ECCC)[1] is offering Wikimedia Canada funding until March 31, 2021 for its project entitled: "ECCC Weather Observations in Wikimedia Commons".

The inclusion of government and scientific data in Commons is a world first.


Project stages and objectives


How do we want to use our weather heritage?


How can we influence the rest of the world to import similar open access data into Wikimedia Commons?


How can this data help us to solve some of the climate change issues that affect us?

Wikimedia Canada wants to bring together the general public, the weather community, the open data community, and science educators in the development, use, and dissemination of a century of Canadian weather data.
  • Phase 1 (2019-2020) : import weather data into Commons from 8,756 Canadian observation stations over the past 100 years.
  • Phase 2 (2020-2021) : to enhance the utilization these data, in particular, is to use and disseminate them in Wikimedia projects, including Wikipedia.
