Abstract
Sensitivity of atmospheric PCB congener flux estimates to sampling station data temporal and spatial interpolation is investigated. In order to quantify the interpolation scale effects, three levels of interpolation are compared and error estimates reported. Level 1: annual average atmospheric PCB concentration applied to annual average water PCB concentration for instantaneous flux calculation, no spatial resolution. Level 2: monthly average atmospheric PCB concentration applied to monthly average water PCB concentration for instantaneous flux calculation, with similar to 7250 kilometer resolution (eight spatial zones). Level 3: daily average atmospheric PCB concentration applied to monthly average water PCB concentration for instantaneous flux calculation, with 5 kilometer resolution (2318 spatial zones). Error propagation for atmospheric PCB concentrations is broken down into three major components sampling/analysis error, temporal interpolation error and spatial interpolation error. Insight for sampling station location based on atmospheric PCB concentration variance reduction shows how to reduce flux estimate uncertainty.
