### Additional Evaluation of the 12-km grid resoluti on Meteorological Model Simulation over Georgia 

# 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 associated 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 southeaste rn United States. These improvements are required to be made under provisions of the Regional Haze Rule. Details of this modeling effort, including model perf ormance evaluation is available at http ://www.baronams.com/projects/VISTAS/ . The Georgia Environmental Protection Division (EPD) conducted an internal review of above mentioned meteorological model simulation. The review had two main objectives: 1) Conduct a visual and qualitat ive inspection of the modeling simulations to better understand the simulated meteorology, and 2) perform statistical analysis using software tools currently operational at Georgia EPD, and verify the overall assessment of the VISTAS contractor. This report provides a brief summary of the meteorological modeling effort and presen ts results of the statistical analysis performed by Georgia EPD. Figure 1 VISTAS 12-km resolution modeli ng grid.

## BAMS conducted modeling simulations on a nested grid configuration, 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 and true latitudes at 33 and 45N. The top of the modeling grid was fixed at 50mb. The mode ling grids are shown 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 routinely accurately predicted, and the model showed considerable skill in replicating the state variables. Most of the time the model statistics fell within the “benchmarks” proposed by Emery et al. (2004) 2. The model shows evidence 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 a ppears to be out of phase with the observed cycle. The mode l maximizes cloud coverage at night and minimizes Data & Modeling Unit, Air Protection Branch

## cloud coverage in the aftern oon, while the observations indicate that the exact opposite should occur. 4. The model noticeably overesti mates the amount of summertime precipitation, but not the spatial cove rage of measurable precipitation. 5. Results of this effort should prod uce credible inputs for subsequent air quality modeling.

# Additional Model Pe rformance Evaluation Introduction Meteorological fields produ ced by MM5 are an input to the emissions and air quality models. Their accuracy is thus of cons iderable importance. To quantify how accurately a modeling simulation captur es the observed atmospheric 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 complexity and importance of evaluating meteorological modeling results for air quality applications. It suggests “that states and tribes devote appropriate effort to the process of evaluating the meteorological inputs to the air qualit y model”. It recomme nds comparison of domain wide and/or regional summary st atistics against pr eviously generated meteorological model performance “ben chmarks” Emery (2001) (Tables 5). Scientist and engineers around the world have extensively used the MM5 modeling system for atmospheric research and oper ational weather forecasting. Since MM5 algorithms and modules have undergone si gnificant peer review and testing, an “operational” evaluation of th e modeling system is sufficien t to serve as the basis of evaluating if the system is operating with sufficient reliability to be used in support of SIP development. Operational evaluation can be defined as process of evaluating how accurately a modeling simulation estimate s observed quantities. In the case of a prognostic meteorological model, this amounts to a statistica l analysis of model predictions and surface 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 an d direction, and humidity. The metrics include: Bias Error (B), Gross Error (E ) and Root Mean Square Error (RMSE), Systematic Root Mean Square Error (RMSE s 

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

## ) and Index Of Agreement (IOA). Mathem atical formulation of these variables is provided in Table 4. The surface mete orological data for this analysis was obtained from http ://dss.ucar.edu/datasets/ds472.0 . While reviewing statistics, the reader is ca utioned that summary statistics are useful in making only a general assessment abou t the adequacy of meteorological fields. For example, daily-mean performance statis tics are likely to conceal important hourto-hour variations. Also, summary statisticsdepend upon the number of observationprediction pairs and generally improve wi th larger sampling sizes and longer averaging periods. This is because the pr obability of statistics being affected by extreme values is high in smaller sample sizes. These and other 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 meteorological model output.

## A graphical summary of the daily and hourly mean performance statistics for the 12- km grid resolution modeling simulation is provided in the remainder of this report. Monthly averaged statistics ha ve also been provided in Tabl e 6. Statistics have been computed at monitoring stations that are located within the box shown in Figure 1. These stations are iden tified in Table 8. Discussion and conclusions The results of the statistical analysis are co nsistent with findings 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 are within the benchmarks proposed by Emery (2004) and suggested by U.S. EPA (Table 1). Monthly av erage statistics reveal under prediction in humidity from May through November, an d an over prediction in temperature during the summer months (May through Se ptember). The simulation tends to over Data & Modeling Unit, Air Protection Branch

## predict day-time and night-time temperature, 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 sc ales, together with the issue of data scarcity and representatives might produce ve rification scores that do not adequately represent the quality of mete orological modeling simulati on (Mass, 2002). It should also be pointed out that air quality mode l performance evaluation serves as an additional check on how accu rately the meteorological model was able to capture the observed atmospheric dynamics during a particular time period. In an unlikely event of an unusually poor air quality model performance, it is reasonable to further investigate the performance of meteorological model.
