Climate Informatics 2023

Reproducibility Challenge

Welcome to the 2023 Climate Informatics Reproducibility Challenge!

We provide below the key info of the challenge.

📌 For further details visit the official website at this link.


Registration is now open for participants (teams) and reviewers at this link (go to Application form) through 22 April @ 23:59 28 April @ 23:59 AOE and 13th May @ 23:59 AOE, respectively. Read on to learn more about the challenge!


This year’s challenge aims to build community, facilitate collaboration, and advance open science within the Climate Informatics community, continuing the tradition of an annual Climate Informatics conference-associated hackathon whilst drawing inspiration from The ML Reproducibility Challenge.


In this year’s challenge, teams of 2-4 will collaborate to create a notebook which reproduces the key contributions of a published environmental data science paper for eventual integration in the open-source Environmental Data Science (EDS) Book. Over the course of a month, teams will locate the data and code associated with their chosen paper; train, validate, and test the models used in the paper; visualise key results from these experiments; discuss their work with peer reviewer(s); and ultimately weave together a narrative illuminating the value of open science which culminates in a citeable, DOI-tagged notebook. Teams will further have the opportunity to network and exchange technical Q&A with fellow participants in weekly drop-in socials throughout the competition. Check out this notebook in the EDS book which reproduces IceNet (Andersson, 2021) for an example of what you’ll be working towards!


Teams may choose to join the challenge through one of two tracks:

  1. Pre-Approved Paper Track: Reproduce a paper pre-approved by the Organising Committee to have sufficient data and code availability. Pre-approved papers are listed in alphabetical order here.
  2. Participant-Suggested Paper Track: Suggest a paper to reproduce, subject to approval by the Organising Committee. This mechanism is designed to ensure teams choose papers which are realistic to reproduce in a month.


All notebooks within the EDS book are peer-reviewed to maintain a high standard of scientific integrity. A pool of peer reviewers consisting of original authors of pre-approved papers, reviewers for the Climate Informatics conference, and other members of the Climate Informatics and EDS book communities will begin working with participants at the two-week mark of the competition to sharpen the submission and ensure it is ready for publication in the EDS book following the competition.


Submissions to both tracks will be judged together by the following panel of environmental data science experts on the basis of their adherence to open science and FAIR practices, adherence to the objectives of the EDS book, and tutorial contributions, adjusted to consider the amount of resources provided by the authors of the original paper.


Each member of the winning team will receive a free book of their choosing (up to £500 in value split across the winning team) published by Cambridge University Press. Note that all participants who complete the challenge will have authorship on a citeable, DOI-tagged notebook within the Environmental Data Science (EDS) Book for listing on their CV.


Registration for the challenge is free and does not require registration to the 12th International Conference on Climate Informatics held in Cambridge from 19-21 April, though we do encourage researchers interested in the topics covered by the conference to attend in-person or virtually. Registration for the conference is open through 3 April here.
