Invitation to Contribute to Paper: "Advancing Heliophysics Modeling through Open Science"

The Heliophysics Open Modeling Environment (HOME) initiative was launched during the CCMC 2024 Open Science in Modeling Workshop (June 2024). Block agenda with links to the open science session descriptions can be found here. 

Discussions at the workshop addressed the role of models in heliophysics and space weather; the need to strengthen the modeling community; challenges and opportunities for implementing open science practices in modeling; and the resources, infrastructures, and support that heliophysics and space weather modelers need to maximize scientific return from open science implementations.

Discussions continued during the ISWAT 2025 Working Meeting (February 2025), where participants suggested including HOME as one of ISWAT’s overarching activities.

A paper, “Advancing Open Science in Heliophysics Modeling,” building on these discussions, is in preparation. The intended submission to Space Weather is at the end of November 2025.

Model developers are invited to contribute to a section dedicated to model development stories, tentatively titled “Successes and Challenges in Open Science in Heliophysics Modeling: Modelers’ Perspective.”

Guidelines for contributions (a few paragraphs, not to exceed one page):

  • Brief model description with reference(s) (10–15 lines or fewer).
  • How has your model advanced open science (e.g., open development and/or open use)?
  • Lessons learned and outlook from your open science experience.

We are also planning a section on the importance of open access to observational data ready to be used for model inputs, model validation, and data assimilation.

International participants are invited to contribute by providing references to national policies/programs on heliophysics and space weather modeling, and short citations from those documents relevant to topics in our paper. There are already many citations from U.S. documents on model importance and open science (e.g., the U.S. Heliophysics Decadal). We seek additional references to other national or international documents (including roadmaps similar to the U.S. Decadal) with citations on relevant topics (e.g., importance of models, open science, etc.).

It would be especially valuable to include citations from European documents on the topics discussed in the paper—particularly open science policies and the role of models—or any documents similar to the U.S. Decadal.

Sign up to join HOME and/or contribute to the paper: https://bit.ly/signupHOME.

After signing up, you will receive a link to the paper draft. Contributions can be inserted directly into the draft or sent by email to Masha Kuznetsova and Claudio Corti.

Deadline for contributions: October, 2025
