The Canadian Meteorological and Oceanographic Society’s 2019 Congress will be held in Montreal July 8th – 11th, jointly with the International Union of Geodesy and Geophysics’ (IUGG) 27th General Assembly.


2019 marks the 100th anniversary of the IUGG and to celebrate this momentous occasion, the who’s who of the international weather and oceanographic community will gather in Montreal during that period. The Meteorological Service of Canada (MSC), part of Environment and Climate Change Canada (ECCC), will be hosting an OPEN DATA FORUM and a hackathon, METEOHACK, during that week.


The OPEN DATA FORUM is a special opportunity for experts and data enthusiasts from Canada and from around the world to come together, learn from each other and contribute to promote the ECCC-MSC open weather, climate and environmental data.


METEOHACK is an intense 48-hour development sprint where innovators from across Canada compete to demonstrate the power of earth science data.


Winning teams will be awarded $10,000 in prizes.


From July 8th to July 11th, developers, data scientists, technology professionals, researchers, experts, academics and all weather data enthusiasts are invited to explore the near universal influence of environmental factors like weather and climate on Canadians using the data collected and generated by ECCC-MSC. It is free to participate!


In consideration of Climate Change and to encourage the meaningful and productive use of earth science data, METEOHACK aims to inspire innovations in four categories:


The Earth and Us: Combine Earth Science data and/or meteorological/climate data with sociological and/or economic information to generate new understandings and perspectives on human-environment interactions.


New Audiences: Find new applications for a diverse audience that generally does not care about the Earth science and meteorological data: young audiences, students, non-experts and diverse socio-cultural communities.


Warning! Danger Ahead!: Analyze Earth Science data and weather data to assist in monitoring natural disasters and phenomena associated with health risks, and to assess their impacts on life and property.


Artify the Earth: Interpret our Earth Science data and weather data artistically to create beautiful data visualisations, virtual reality experiences, music, or unique pieces of art.


All eligible submissions must be submitted in one of the above categories.


Mentors will be on-site to support participants to access and use datasets available in the ECCC-MSC open data offer and climate archives, and to guide the data users in selecting the most relevant datasets for their project. Mentors will help participants in finding creative answers to critical issues they are trying to solve, and to elaborate on how these issues could be solved through the use of Open Data.



Participants can take part in METEOHACK in one of two ways:

    • 100 participants can register to compete at the event location, the Phi Centre in Montreal.
    • 100 additional participants can participate virtually in the hackathon from anywhere in Canada.

We encourage as many participants as possible to join us at the event location for the best hackathon experience. Food and beverages will be provided during most of the event, and you’ll get an opportunity to network with other participants, mentors, external MSC data users, and international representatives of the International Joint Canadian Meteorological and Oceanographic Society (CMOS) and the International Union of Geodesy and Geophysics (IUGG).


Physical space is limited at the METEOHACK hub to 100 participants and we strongly encourage you to register early to secure your spot.



We highly recommend all participants attend the OPEN DATA FORUM in order to learn more about the open data available for the competition and to learn the best practices to manipulate them efficiently.


We recommend all participants explore the three main data resources before the competition starts to get familiar with the portal and the datasets available. There are thousands of  datasets to choose from and going through all of them might very well take 48 hours and leave you no time to develop your submission.




Geospatial Web Services: GeoMet

  • Access to MSC & CCCS data via international web services standards / interoperable API’s

  • Target audience has some weather and/or IT knowledge

The presentations of the day: Open Data Forum

  • You can access them here, and download all of the presentations.
  • The demo we did during the forum can also be very useful, you can download it here.
  • All of the live-streams of the presentations are here.

NEW!! The Exceptional MSC Open Data Documentation (version 2.0) now on GitHub:

available here.

Don’t forget that METEOHACK is all about the mash-up of earth science data with other data sets to extract maximum value and insight.



  • The Open Government Portal is a true treasure-trove of data. Search to find what is most relevant to your idea, learn how to work with datasets and explore what others have done with open data across the country right here:
  • To start, check out the Open Data 101 page here, visit the Apps Gallery to get inspired here or brush up on you data skills by visiting the Working with Data and Application Programming Interfaces page here.
  • Head over to the Open Government Across Canada page here and find great provincial or municipal datasets to compliment your application and increase your chances of winning.
  • Didn’t find the dataset you were looking for? Make sure you let the Government of Canada know by requesting it here
