NADP Conferences
Every year the NADP organizes a scientific symposium where researchers share the results of their work in precipitation chemistry and atmospheric deposition. Previous to 2025, the Symposium was held in the fall, starting in 2026, the scientific symposium will be held during the spring. In 2025, there will be no scientific symposium, in order to accommodate the change in scheduling.
