Shrinking a Wet Deposition Network (1994)

Abstract:

We use the spatial-temporal model described in Oehlert (1993) to choose good sets of can­didate stations for deletion from the NADP / NTN network. We use three criteria: that the sum of 11 regional trend estimate variances be as small as possible, that the sum of local trend estimation variance be as small as possible, and that the sum of local mean estimation variance be as small as possible. Good choices of stations for deletion result in a modest increase in criteria (about 7% to 12%) for 100 stations deleted from the network, while random sets of 100 stations can increase criteria by a factor of 2 or more.
