NASA CCMC Model Validation Efforts Toward Open Science

<p>The NASA Community Coordinated Modeling Center (CCMC) is a multi-agency partnership aimed at fostering the dissemination and advancement of space science and space weather modeling. The CCMC hosts an extensive suite of state-of-the-art ionospheric models developed by the broad space weather and aeronomy community and serves as an impartial arbiter to facilitate the validation, testing, and enhancement of space weather models for eventual integration into space weather forecasting. To create a collaborative culture and promote the dissemination of scientific knowledge, CCMC is dedicated to facilitating open data and science, making scientific research transparent and easily accessible. In this study, we will present a CCMC ionosphere model validation project during the 2013 March and 2021 November storms. 14 ionospheric models, including empirical, physics-based, and data assimilation (DA) models, hosted by the NASA CCMC, NOAA Space Weather Prediction Center, and NASA Jet Propulsion Laboratory, are validated. The scientific results are released at CCMC website in the form of executable paper using the Jupyter notebook. The use of executable paper enhances the reproducibility of scientific findings and firmly supports open science practices, paving the way for more transparent and collaborative research.</p&gt
