Always Open
We’re a group of creative thinkers who have built a business to change the world.

As suggested by our name, we are putting as much knowledge, learning and data out in the open as we can.  We believe that no one can mitigate climate change alone, and through curating our code as a usable open source project, our work stands to have its greatest impact and widest reach. 

What is the impact of Open?

The climate emergency is waiting for no one.  To allow us and all the world to work globally and at speed, we aim to: 

  • Free up knowledge and data to be shared
    Closed intellectual property can be a huge blocker to progress.  Making our work freely accessible and working out in the open, we invite anyone around the world to benefit from our work or to improve on what we have done. Access to data is often a barrier to entry for new entrants to a field - by publishing all the data we are allowed to, we break down these barriers and hugely expand the pool of people who can work on a problem.  
  • Enable deep collaboration
    There are thousands of people out there passionate about addressing climate change. But it’s hard to get involved. By making code, data and domain knowledge publicly available, we invite others to contribute to the work we are doing. Open source projects are now best in class in many fields, from Linux to Python to Apache. We all work better when we work together. By being completely open, we allow many to contribute to accelerate the pace of development.  

Open Code

As we work to establish an impactful open source project, we perform all our development completely in the open. Our code, GitHub issues and plans are all published and documented on  Projects range from our DataPipes to implementations of well-known academic papers from Google Research and Google Brain, to our own forecasting techniques.

We want people to use our code or have a go at tackling a few GitHub issues. If you’re wondering where to start, here is a list of good first issues!

Open Data

Data is the lifeblood of machine learning.  And energy data is often difficult to obtain, messy to work with and not easily shared.  At Open Climate Fix we are sharing as much data as we are legally able to.  In many cases these are extremely large datasets not usually available to the public.  We have datasets on numerical weather predictions (NWP), satellite imagery and PV time series spanning the globe in many cases.  

We try to document this data as well as possible, and have put considerable effort into processing the data into a format that makes it as usable as possible.  

Please visit our data on to see the data we’ve published. On Hugging Face we have 10s of terabytes of NWP data, 8 years of satellite imagery at 5-minute intervals covering all of Europe and some of Africa and the Middle East as well as multi-year datasets of precipitation radar data covering the UK, Sweden, and the US.
