本文介绍了美国环境保护署（EPA）大气模拟与分析部（AMAD）的科学家开发的大气模型评估工具（AMET）v1.1的详细情况。AMET最初是为了评估第五代中尺度模式（MM5）和天气研究与预报（WRF）气象模式输出的性能而开发的，后来扩展到包括评估社区多尺度空气质量（CMAQ）模式输出数据的能力。AMET旨在利用几个开源软件包，这些软件包组合使用，以1）在时间和空间上配对建模和观察值，2）将这些配对的数据集存储在易于访问和搜索的数据库中，3）使用统计软件包访问和分析这些数据。通过这个过程。AMET能够为评估气象和空气质量模式预测提供一种方便的方法。使用可搜索的关系数据库可以将整个数据集快速地划分为当前分析最感兴趣的数据，这是一个在不使用数据库的情况下通常繁琐且耗时的过程。除了常见的汇总统计量（例如RMSE、偏倚和相关性），AMET中可用的许多分析功能包括散点图、时间序列图、箱形图和空间图，作为操作模型评估的一部分。此外，在AMET中还提供了几个独特的分析功能，该系统提供了一个框架，用户可以在其中扩展当前的功能以进行自己的定制分析。虽然AMET是专门为MM5、WRF和CMAQ模式输出而设计的，但它可以很容易地进行修改，以处理其他气象和空气质量模式的输出数据。爱思唯尔有限公司出版
This paper describes the details of the Atmospheric Model Evaluation Tool (AMET) v1.1 created by scientists in the Atmospheric Modeling and Analysis Division (AMAD) of the U.S. Environmental Protection Agency (EPA). AMET was first developed to evaluate the performance of the 5th Generation Mesoscale Model (MM5) and the Weather Research and Forecasting (WRF) meteorological model output and was later extended to include capabilities for evaluating output data from the Community Multiscale Air Quality (CMAQ) model as well. AMET is designed to leverage several open-source software packages that are used in combination to 1) pair the modeled and observed values in time and space, 2) store these paired datasets in an easily accessible and searchable database and 3) access and analyze these data using a statistical package. Through this process. AMET is able to provide a convenient method for evaluating meteorological and air quality model predictions. The use of a searchable, relational database allows the entire dataset to be quickly subset into only those data that are of the most interest for the current analysis, a process that is often tedious and time consuming without the use of a database. In addition to common summary statistics (e.g. RMSE, bias, and correlation), several of the many analysis features available in AMET include scatter plots, time series plots, box plot and spatial plots as part of operational model evaluation. Additionally, several unique analysis functions are also available in AMET, and the system provides a framework within which users may extend the current functionality for their own custom analyses. While AMET was designed to work specifically with MM5, WRF and CMAQ model output, it could easily be modified to work with output data from other meteorological and air quality models.
