NARSTO SOS99NASH TVA Surface Meteorology and Chemistry Data

Table of Contents:

1. Data Set Description:

Tennessee Valley Authority (TVA) operated two enhanced (Level 2) surface-level monitoring stations during the 1999 Nashville/Middle Tennessee Field Study. One of the level 2 stations is located on the top of the James K. Polk Building in downtown Nashville. The other level 2 station is located about 40 miles west of Nashville near Cumberland Furnace in Dickson County. Gas measurements (5-minute averaged concentrations) include sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), nitrogen oxide (NO), nitrogen dioxide (NO2), and total oxides of nitrogen (NOY). The meteorological measurement package includes wind speed (WS), wind direction (WD), temperature (T), relative humidity (RH), and solar radiation (RAD).

2. Sample Data Record/Data Format:

Data files are in the NARSTO Data Exchange Standard (DES) format that is described in detail on the NARSTO Quality Systems Science Center (QSSC) web site [ http://cdiac.esd.ornl.gov/programs/NARSTO/]. The files follow a tabular layout and are stored as ASCII comma-separated values files (.csv). The DES does not rely on row position to identify specific information, but uses a tag to describe the information contained in the row. The DES is a self-documenting format with three main sections: the header contains information about the contents of the file and the data originator; the middle section contains metadata tables that describe/define sites, flags, and other codified fields; and the final section is the main data table that contains key sampling and analysis information and the data values. Descriptions of the standardized metadata fields are also available on the QSSC web site.
