| Downloadable | Castnet Filter Pack Weekly Concentrations | This project will assess the relationship between a proposed index of aquatic acidification due to airborne pollutants and the concentrations in air of ammonium, nitrogen oxides and sulfur oxides. | Weekly concentrations of NOx, SOX, Ca, Na, Mg, K and Cl for use in Aquatic Acidification model | 2012-11-13 (ongoing) |
| Downloadable | NADP Ammonia Concentration- one sampler | Provide a consistent, long-term record of ammonia gas (NH3) concentrations from Vermont for use in the aquatic acidification model | Weekly ammonia concentration from single sampler | 2012-11-20 (ongoing) |
| Downloadable | NADP Average Ammonia Concentration- more than one sampler | Provide a consistent, long-term record of ammonia gas (NH3) concentrations from Vermont for use in the aquatic acidification model | Replicates of ammonia concentration | 2012-11-20 (ongoing) |
