2025 DASH/IHDEA meeting: 20-24 October in San Antonio, Texas

Calling all software developers and scientists who are interested in algorithms, software and data systems related to heliophysics (solar physics, space physics, geospace and related sciences)! Come see what your colleagues are working on!

Mark your calendars! 20-24 October 2025 is the DASH (Data Analysis and Software in Heliophysics) and IHDEA (International Heliophysics Data environment Alliance) annual meetings. There is also an early career mixer Sunday night (Oct 19).

The DASH 2025 website will launch in January 2025. DASH is funded by NASA.

Looking forward to seeing you!!

DASH serves as a forum for scientists and software developers to present and discuss algorithms, software, and data systems used in the acquisition, reduction, analysis, and dissemination of data for Heliophysics, including space and ground-based measurements as well as models. The meeting connects practitioners across institutions, and international participation is key to success.


DASH 2024 ran October 14-18, 2024 at ESAC in Madrid Spain, followed by IHDEA 2024.
