Uncertainty in change over time in sulfate in atmospheric deposition in NY as a function of
sampling intensity (21 stations = 100%)
Uncertainty in change over time in Adirondack lake nitrate
as a function of sampling intensity (50 lakes monthly = 100%)
Uncertainty in Forest Biomass in W6
as a function of the number of plots sampled
