Summary
Abstract: M3 - Pollution Flux Measurements

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.

In support of the 1995 Southern Oxidants Study (SOS) Nashville/Middle
Tennessee Ozone Study, continuous 30-minute average eddy correlation
flux measurements were collected for ozone, sulfur dioxide, and carbon
dioxide at a south central Kentucky site (36.83 N, 87.03 W) near
Keysburg, KY from June 22 through August 10, 1995. All measurements
were made primarily above soybeans. Nitric acid gradients were
measured for selected 2-hour periods between 1 and 8.5 meters and
subsequently converted to fluxes. Heat flux, water flux, soil flux,
soil storage, and net radiation were measured to characterize the
energy budget. Additionally, 30-minute average values of ozone and
sulfur dioxide concentrations, wind speed, wind direction, solar
radiation, precipitation, surface wetness, relative humidity,
temperature gradient, etc. were made to support evaluation of the
inferential dry deposition model. Leaf area index, stomatal
resistance, and vegetation height were also measured.


The NOAA Atmospheric Sciences Modeling Division (ASMD), a division of
NOAA's Air Resources Laboratory, is primarily responsible for the
pollution meteorology research for the U.S. Environmental Protection
Agency (EPA).

The study was conducted from June 22, 1995 through August 10, 1995.

The Tennessee Valley Authority (TVA) was the coordinator for the 1995
Southern Oxidants Study Nashville/Middle Tennessee Ozone Study. See:
