Table 3 Statistical scores of the meta-model approximation results compared to the scores of the model chain using the full air quality model
From: Meta-modeling of a simulation chain for urban air quality

|---|---|---|---|
\(c({\mathbf {p}})\) vs. \({\hat{c}}({\mathbf {p}})\) | Statistical scores over 1-month simulations | ||
Over the full grid | MNRMSE (14) | \(\sqrt{\text {NMSE}}\) (11) | Correlation (12) |
Meta-model vs. full model chain | 0.274 | 0.25 | 0.93 |
At receptor locations | NRMSE (10) | \(\sqrt{\text {NMSE}}\) (11) | Correlation (12) |
Meta-model vs. full model chain | 0.22 | 0.18 | 0.96 |
