Background

Baron Advanced Meteorological System (BAMS) 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 focused 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, including model performance 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 qualitative 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 presents results of the statistical analysis

performed by Georgia EPD.

(Dudhia, 1989; Grell, 1994). Model configuration (Table 1) for this simulation was

determined through sensitivity tests that were designed to gain a better

understanding of the model response to the selection of PBL and land surface

schemes. The results of these sensitivity tests are documented elsewhere (Olerud,

2005).

BAMS conducted modeling simulations on a nested grid configuration, with two grids

at 36 and 12-km grid resolution. These 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 modeling grids are shown in Figure 1. Grid

configuration details have been provided in Tables 1 and 2.

BAMS conducted extensive model performance 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 particularly 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 model maximizes cloud coverage at night and minimizes

cloud coverage in the afternoon, while the observations indicate that the exact

opposite should occur. 

4. The model noticeably overestimates the amount of summertime

precipitation, but not the spatial coverage of measurable precipitation. 

5. Results of this effort should produce credible inputs for subsequent air

quality modeling.

Additional Model Performance Evaluation

Introduction

Meteorological fields produced by MM5 are an input to the emissions and air quality

models. Their accuracy is thus of considerable importance. To quantify how

accurately a modeling simulation captures the observed atmospheric dynamics,

predictions of key atmospheric variables are compared against land and/or satellite

based observations. While performance evaluation methodology and goals may vary

from application to another, performance evaluation 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 quality model”. It recommends comparison of

domain wide and/or regional summary statistics against previously generated

meteorological model performance “benchmarks” Emery (2001) (Tables 5). 

Scientist and engineers around the world have extensively used the MM5 modeling

system for atmospheric research and operational weather forecasting. Since MM5

algorithms and modules have undergone significant peer review and testing, an

“operational” evaluation of the modeling system is sufficient 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 estimates observed quantities. In the case of a

prognostic meteorological model, this amounts to a statistical 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 and direction, and humidity. The metrics

include: Bias Error (B), Gross Error (E) and Root Mean Square Error (RMSE),

Systematic Root Mean Square Error (RMSEs), Unsystematic Root Mean Square Error

(RMSEu) and Index Of Agreement (IOA). Mathematical formulation of these variables

is provided in Table 4. The surface meteorological data for this analysis was

obtained from http://dss.ucar.edu/datasets/ds472.0.

While reviewing statistics, the reader is cautioned that summary statistics are useful

in making only a general assessment about the adequacy of meteorological fields.

For example, daily-mean performance statistics are likely to conceal important hourto-hour variations. Also, summary statistics depend upon the number of observationprediction pairs and generally improve with larger sampling sizes and longer

averaging periods. This is because the probability 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 benchmarks proposed in Emery et al., (2001) should

not be used in a “pass/fail” model, but 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 have also been provided in Table 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 findings of the contractor

discussed earlier. Overall, the simulation is able to capture meteorological conditions

observed during the study period with the 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 average statistics reveal under prediction

in humidity from May through November, and an over prediction in temperature

during the summer months (May through September). The simulation tends to over

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 parameterization (planetary boundary layer, surface

heat, and moisture budgets) at smaller scales, together with the issue of data

scarcity and representatives might produce verification scores that do not adequately

represent the quality of meteorological modeling simulation (Mass, 2002). It should

also be pointed out that air quality model performance evaluation serves as an

additional check on how accurately 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.
