Registration open: NDACC 35th anniversary symposium, Virginia Beach, VA, US, 27-30 October 2025

An International Symposium Celebrating 35 Years of Global Atmospheric Research Enhanced by NDACC/NDSC Observations

The 2025 NDACC Symposium, hosted by Hampton University, celebrating 35 years of atmospheric research fostered by Network observations, will provide a forum to exchange information on the latest scientific achievements using NDACC and related observations, and to present NDACC’s measurement strategy for the future. We expect 150-200 scientists to participate in person, with more joining online.

NDACC 2025 Registration is now open, Early Bird registration closes 29 August, 2025.
