Inverse Dispersion for an Unknown Number of Sources: Model Selection and Uncertainty Analysis

Figure 2

Univariate (diagonal) and bivariate (off-diagonal) marginal posterior distributions of the source parameters, namely, alongwind location 𝑥 𝑠 , crosswind location 𝑦 𝑠 , and emission rate 𝑞 𝑠 that characterize sources 1 (a), 2 (b), 3 (c), and 4 (d) obtained from samples of source model 𝑚 𝑁 ( 𝑁 = 4 ) drawn from the posterior distribution 𝑝 ( 𝜃 𝑚 𝑁 , 𝒟 , 𝐼 ) ([cf. Figure 1(d)).
