Data Product



Ambient Air Concentrations Annual average ambient air concentrations of particles and gases, as measured by CASTNET.
Dry Deposition Annual average dry deposition, as the product of measured concentrations from CASTNET and modeled CMAQ deposition velocities and concentrations using the TDep hybrid method.
Precipitation Chemistry Annual average precipitation-weighted concentrations of major ions in precipitation, as measured by NADP/NTN.
Wet Deposition Annual wet deposition, as the product of concentrations measured by NADP/NTN and precipitation amount estimated from the PRISM model.
Total Deposition Annual average total deposition estimates that combine dry deposition and wet deposition grids following the TDep hybrid method.
