Figure 9-9. Comparison of spatially-averaged observed and modeled tracer concentrations in southwest Texas
(in the same format as Figure 9-8). The tracer concentrations were averaged over the six 6-hour monitoring
sites: San Vicente, K-bar, Persimmon Gap, Marathon, Fort Stockton and Monahans Sandhills.
