Tracer Experiment Data Archive
Most of the data files are simple formatted ascii files
(.dat). Some may have been compressed using PKZIP (.ZIP)
for PC's or for UNIX as a compressed tar file (.tar.Z).
The file formats are described in the corresponding data
reports. Each report has been scanned and saved in PCX
format, one file per page, compressed into a ZIP file.
In addition most reports have been converted to PDF for
direct viewing. In addition, a set of CDs containing the
tracer data are available by special request under the
Data Archive of Tracer Experiments and
Meteorology (DATEM) program.
METREX Data Archive
The METREX experiment consisted of 6 hour emissions
of perfluorocarbons simulaneously, from two different locations,
every 36 hours. The tracer release locations were in suburban
Washington, D.C, while 8 hour air samples were colleced at
three locations within the urban area. The experiment ran
for one full year. In addition monthly air concentration
samples were collected at about 60 locations throughout the
region.

The CAPTEX experiment consisted of 5 perfluorocarbon
releases from Dayton, Ohio, and 2 from Sudbury, Ontario.
Six hour average air samples were collected at sites over
the northeastern U.S. for each release. In addition extensive
aircraft tracer measurements are available.

The ANATEX experiment was conducted for a three month
period and consisted of 3 hour perfluorocarbon releases simultaneously
from Glasgow, Montana, and St. Cloud, Minnesota. Tracer releases
were made every 60 hours regardless of the meteorological
conditions. Air concentrations were measured as daily averages
at most weather stations in the eastern half of the U.S.
and southern Canada. In addition, aircraft tracer measurements
were made near each release location. Other sampling was
conducted along an arc of towers, as well as at a few remote
locations on the west coast of the US and Europe.

The ACURATE experiment consisted of measuring the Krypton-85
air concentrations from emissions of the Savannah River Plant.
Twice-daily (12h) average air concentrations were collected
for over one year at 5 locations along the east coast of
the U.S.
