Figure C‐ ‐9. Global model m perforrmance statistics for thee CAMx senssitivity testss without ussing the PiG ssubgrid‐scale e puff moduule for CAPTTEX Release 3. C.3.3 SPATIAL PERFO ORMANCE FFOR CTEX3 PPIG EXPERIMMENTS Figure C‐ ‐10 displays the CAMx sppatial modell performance statistics for the senssitivity tests that were runn using the PiG P subgrid‐sscale puff moodule. For the FMS stattistic, the CMMAQ Kz/BOTTT combination has the best perforrmance at 366.2%. TKE/BBOTT and TKE/PPM followed closely with FMS scorres of 36% and 35.6% reespectively. OB70 exhibits the pooreest performaance with 233.5% for FMS. For the FFAR statistic, ACM2/Bottt has the besst score (61. 5%) followed by TKE/BOOTT and ACM2/PPPM (62.8% and a 63% resppectively). OOB70 exhibitted the poorrest performmance with a 72% FAR. For the POD me etric, the TKEE/BOTT commbination performs substantially bettter than thee other Kz/ /advection solver s combiinations (44. .4%). Both OOB70 scenariios showed tthe poorest performaance at 13.9%. For the TTS spatial meetric, the CMMAQ/PPM exxhibits the beest score with 30.6% followed by TK KE/BOTT andd CMAQ/BOOTT(25.4% annd 23.3% resspectively). OB70 again performss poorest with a TS valuee of 10.2% foor both adveection solver combinatioons. Consistent with the ETEX spatial results, theere are muchh smaller diffferences in the model pperformancee using thee two advect tion solvers ffor the POD and TS statiistics compaared to differrences betwween Kz optionns. In summary, the effe ect of using tthe CAMx suubgrid scale puff modulee appears to slightly deggrade performaance in comparison to thhe NoPiG exxperiments. A similar paattern was nooted in the spatial sttatistics com mpared to thee NoPiG expperiments wiith the ACM2, CMAQ, annd TKE Kz algorithmms performin ng similarly, with the oldder OB70 opption exhibiting much pooorer overalll performaance. 12
