Meeting Agenda

IHDEA is about science.

The goal of the International Heliophysics Data Environment Alliance (IHDEA) is to encourage the use of common standards and services in order to enable sharing of data and to enhance science.

The idea of IHDEA has its origin in NASA's 2013-2022 Solar and Space Physics Decadal survey which identified that science is best served by "instant unfettered access to a wide array of datasets from distributed sources in a uniform, standardized format". Key to achieving this goal is to have the following:

  • full involvement of data providers
  • establishing data systems driven by community needs and standards
  • availability of coordinated, user-friendly analysis tools
  • reliable high-performance computing facilities and data storage
  • uniform terminology and adequate documentation describing data products and sources
  • flexible, interoperable, and interconnected data archives, modeling centers, and virtual observatories
  • effective communication among data providers, national and international partners, and data users

The role of the IHDEA is to engage the community, foster communication, and to identify the standards and services which will best served the science needs.

We hope you enjoy your visit to the IHDEA and welcome your comments.

Data Environment

The Data Environment has many components that need to function cohesively in order to enable scientific discovery. The IHDEA recommends these components:
