M7 - National Weather Service ETA Model Forecasts
The Southern Oxidants Study (SOS) conducted a major field research
campaign in Nashville/Middle Tennessee area in June and July 1994 and
1995. The goal of this study was to improve scientific understanding
of the processes that control the production and distribution of ozone
in the troposphere.
The ETA 48-hour daily weather forecasts provided by the National
Weather Service for June 14 through Juky 20, 1995 were post-processed
by the NOAA Air Resources Laboratory to provide the grid structure
required for the initialization and four dimensional data
assimiliation (FDDA) executed in the Regional Atmospheric Modeling
System (RAMS). RAMS was run each day to predict the passive pollution
dispersion over the Nashville/Middle Tennessee region, but can be
rerun for any other location in the Southeast using the same
post-processed ETA grids. Both post-processed ETA grids and RAMS
outputs are archived for the period above.
The study was conducted from June 14, 1995 through July 20, 1995.
The Tennessee Valley Authority (TVA) was the coordinator for the 1995
Southern Oxidants Study Nashville/Middle Tennessee Ozone Study.

M7——美国国家气象局（National Weather Service）ETA模式预报数据集
南部氧化剂研究计划（Southern Oxidants Study, SOS）于1994年及1995年的6、7月间，在田纳西州纳什维尔与中田纳西地区开展了大型野外实地研究。本研究的核心目标是深化对流层臭氧生成与分布控制过程的科学认知。
1995年6月14日至7月20日期间，美国国家气象局提供的ETA逐日48小时天气预报，经美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）空气资源实验室（Air Resources Laboratory）后处理，得到了区域大气模拟系统（Regional Atmospheric Modeling System, RAMS）中开展初始化与四维数据同化（Four Dimensional Data Assimilation, FDDA）所需的网格结构。研究人员每日运行RAMS以模拟纳什维尔及中田纳西地区的被动污染扩散过程，且可利用同一套经后处理的ETA网格场，重新模拟美国东南部任意其他区域的污染扩散。上述时段内的经后处理ETA网格场与RAMS模拟结果均已归档留存。
本次研究的实施时段为1995年6月14日至7月20日。
田纳西河谷管理局（Tennessee Valley Authority, TVA）为1995年南部氧化剂研究计划——纳什维尔及中田纳西臭氧研究的协调单位。
