# Background Baron Advanced Meteorological System (B AMS) was awarded contract by Visibility Improvement State and Tribal Association of Southeast (VISTAS) to perform annual meteorological modeling simulations and a ssociated technical analysis. This effort was intended to support activities focuse d on the development of emission control strategies aimed at ensuring better air quality/visibility in national parks and protected areas throughout the southeastern United States. These improvements are required to be made under provisions of the Regional Haze Rule. Details of this modeling effort, in cluding model performance ev aluation is available at http://www.baronams.com/projects/VISTAS/ . The Georgia Environmental Prot ection Division (EPD) conduc ted an internal review of above mentioned meteorological model simulation. The review had two main objectives: 1) Conduct a visual and qualit ative inspection of th e modeling simulations to better understand the simu lated meteorology, and 2) perform statistical analysis using software tools currently operationa l at Georgia EPD, and verify the overall assessment of the VISTAS contractor. This report provides a brief summary of the meteorological modeling effort and pres ents results of the statistical analysis performed by Georgia EPD. Figure 1 VISTAS 12-km resolution modelin g grid.

Model configurat ion (Table 1) for this simulation was determined through sensit ivity tests that were de signed to gain a better understanding of the model response to the selection of PBL and land surface schemes. The results of these sensitivit y tests are documented elsewhere (Olerud, 2005).

## BAMS conducted modeling simulations on a ne sted grid configurat ion, with two grids at 36 and 12-km grid resolution. Thes e grids have a Lambert Conformal map projection with origin at 47N and 90W an d true latitudes at 33 and 45N. The top of the modeling grid was fixed at 50mb. The mo deling grids are show n in Figure 1. Grid configuration details have been provided in Tables 1 and 2. BAMS conducted extensive model performan ce evaluation. They made the following conclusions. 1. Generally speaking, MM5 performed quite well at both 36-km and 12-km resolutions. Synoptic features were ro utinely accurately predicted, and the model showed considerable skill in replic ating the state variab les. Most of the time the model statistics fe ll within the “ben chmarks” proposed by Emery et al. (2004) 2. The model shows evid ence of being adversely affected by poor soil initialization at times. This is particul arly evident for September and November. The model is noticeably cold biased in the winter months. This appears to be related to the manner in which soil temperatures are initialized. 3. The summertime diurnal cloud cycle appears to be out of phase with the observed cycle. The mode l maximizes cloud coverage at night and minimizes

## 5 cloud coverage in the afternoon, while th e observations indica te that the exact opposite should occur. 4. The model noticeably overestim ates the amount of summertime precipitation, but not the spatial cove rage of measurable precipitation. 5. Results of this effort should produce credible inputs for subsequent air quality modeling.

# Additional Model Pe rformance Evaluation Introduction Meteorological fields produced by MM5 are an input to the emissions and air quality models. Their accuracy is thus of considerable impo rtance. To quantify how accurately a modeling simulation captur es the observed at mospheric dynamics, predictions of key atmospheric variables ar e compared against land and/or satellite based observations. While performance ev aluation methodology and goals may vary from application to another, performance eval uation is considered an integral part of any meteorological modeling study. Methodology U.S. EPA guidance (EPA, 2007) recognizes the comp lexity and importance of evaluating meteorological modeling result s for air quality applications. It suggests “that states and tribes devot e appropriate effort to the process of evaluating the meteorological inputs to the air qual ity model”. It recommends comparison of domain wide and/or regional summary st atistics against previously generated meteorological model performance “b enchmarks” Emery (2001) (Tables 5). Scientist and engineers aro und the world have extensiv ely used the MM5 modeling system for atmospheric research and op erational weather forecasting. Since MM5 algorithms and modules have undergone si gnificant peer review and testing, an “operational” evaluation of th e modeling system is sufficie nt to serve as the basis of evaluating if the system is operating with sufficient re liability to be used in support of SIP development. Operatio nal evaluation can be define d as process of evaluating how accurately a modeling simulation estima tes observed quantities . In the case of a prognostic meteorological mo del, this amounts to a stat istical analysis of model predictions and surf ace observations. We are using software package METSTAT developed by ENVIRON corporation for calculating model performance statistics. METSTAT computes domain wide surface statistics for temperature, wind speed and direction, and humidity. The metrics include: Bias Error (B), Gross Error (E) and Root Me an Square Error (RMSE), Systematic Root Mean Square Error (RMSE s 

## ), Unsystematic Root Mean Square Error (RMSE u 

## ) and Index Of Agreement (I OA). Mathematical formul ation of these variables is provided in Table 4. Th e surface meteorological da ta for this analysis was obtained from http://dss.ucar.edu/datasets/ds472.0 . While reviewing statistics, th e reader is cautioned that summary statistics are useful in making only a general a ssessment about the adequacy of meteorological fields. For example, daily-mean performance statisti cs are likely to con ceal important hourto-hour variations. Also, summa ry statistics depend upon the number of observationprediction pairs and generally improve with larger samplin g sizes and longer averaging periods. This is because the probability of st atistics being affected by extreme values is high in smaller sample sizes. These and othe r concerns have lead U.S. EPA to recommend that be nchmarks proposed in Emery et al ., (2001) should not be used in a “pass/fail” model, bu t only as a means of assessing general confidence in meteorol ogical model output.

## A graphical summary of the da ily and hourly mean performance statistics for the 12- km grid resolution modeling simulation is provided in th e remainder of this report. Monthly averaged statistics ha ve also been provided in Ta ble 6. Statistics have been computed at monitoring stations that are located within the box shown in Figure 1. These stations are identified in Table 8. Discussion and conclusions The results of the statistical analysis are consistent with findin gs of the contractor discussed earlier. Overall, the simulation is able to capture meteorological conditions observed during the study period with th e adequate level of accuracy. Performance statistics for most days ar e within the benchmarks pr oposed by Emery (2004) and suggested by U.S. EPA (Table 1). Monthly average statistics re veal under prediction in humidity from May throug h November, and an over pr ediction in temperature during the summer months (M ay through September).

## 8 predict day-time and night-time temperatur e, and consistently over-predicts nighttime wind speed. However, the magnitude of these under/over predictions remains small. Deficiencies in physical parameteri zation (planetary boundary layer, surface heat, and moisture budgets) at smaller scales, together with the issue of data scarcity and representatives might produce ve rification scores th at do not adequately represent the quality of meteorological mo deling simulation (Mass, 2002). It should also be pointed out that air quality model performan ce evaluation serves as an additional check on how accurately the meteorologic al model was able to capture the observed atmospheric dyna mics during a particular ti me period. In an unlikely event of an unusually poor air quality model performance, it is re asonable to further investigate the performance of meteorological model.
