NARSTO SOS99 Nashville Tennessee Valley Authority (TVA) Surface Meteorology and Chemistry Data

NARSTO_SOS99NASH_SURFACE_MET_CHEM_DATA is the North American Research Strategy for Tropospheric Ozone (NARSTO) SOS99 Nashville Tennessee Valley Authority (TVA) Surface Meteorology and Chemistry Data product. Data was collected between June 15 and July 16, 1999 during the 1999 Nashville/Middle Tennessee Field Study. TVA operated two enhanced (Level 2) surface-level monitoring stations during the study. One of the level 2 stations was located on the top of the James K. Polk Building in downtown Nashville. The other level 2 station was located about 40 miles west of Nashville near Cumberland Furnace in Dickson County. Gas measurements (5-minute averaged concentrations) included sulfur dioxide (SO2), carbon monoxide (CO), ozone (O3), nitrogen oxide (NO), nitrogen dioxide (NO2), and total oxides of nitrogen (NOY). The meteorological measurement package included wind speed (WS), wind direction (WD), temperature (T), relative humidity (RH), and solar radiation (RAD). North American Research Strategy for Tropospheric Ozone (NARSTO), which has since disbanded, was a public/private partnership, whose membership spanned across government, utilities, industry, and academe throughout Mexico, the United States, and Canada. The primary mission was to coordinate and enhance policy-relevant scientific research and assessment of tropospheric pollution behavior; activities provide input for science-based decision-making and determination of workable, efficient, and effective strategies for local and regional air-pollution management. Data products from local, regional, and international monitoring and research programs are still available.
