Documentation Report
J. G. Droppo, Jr.
An archive for micrometeorological
and tracer dispersion data has been de-
veloped by Battelle, Pacific Northwest
Laboratories for the U.S. Environmen-
tal Protection Agency. The archive is
designed to make the results of exten-
sive field tests readily accessible to EPA
for model testing, development, and
verification efforts.
This report provides documentation
for one volume of data, the Hanford 67-
Series Atmospheric Dispersion Experi-
ments. The entries in this documenta-
tion report are as follows: data set fact
summary, narrative description of ex-
periment and data, special information,
references, description of archive data
files, contacts (names, addresses, and
phone numbers) and standard experi-
ment summary table.
This Project Summary was devel-
oped by EPA's Atmospheric Sciences
Research Laboratory, Research Triangle
Park, NC, to announce key findings of
the research project that is fully docu-
mented in a separate report of the same
title (see Project Report ordering infor-
mation at back).
Introduction
The Meteorology and Assessment Di-
vision of the U.S. Environmental Protec-
tion Agency's (EPA's) Atmospheric Sci-
ences Research Laboratory has initiated
a project to develop and establish an
archive of original experimental data
and documentation for use by atmos-
pheric dispersion and boundary layer
researchers. The archive of data sets
will be useful for evaluating and im-
proving dispersion models, ensuring
the retention of these data for the fu-
ture, and making the data more readily
available to the research community.
This report documents the microme-
teorological and tracer (M&T) data
archive for the Hanford 67-Series at-
mospheric field dispersion experiments
and provides listings of the data set doc-
umentation entries, which are also pro-
vided in ASCII text files on the data
archive tape.
The archive includes both documen-
tation and data. A data set documenta-
tion report is prepared for each archived
data set.
The archive is contained in five or
more files on magnetic tape. These files
consist of header file, three documenta-
tion files, and one or more data files.
The data are entered into the archive
in as close to original form as possible
to maintain a clear link with original
records. The archived data are con-
.tained within a well-defined structure
called a data map. The data map allows
data to be entered in original formats,
while providing the user with a
machine-readable pathway for access-
ing the diverse data formats.

Hanford 67-Series of
Experiments
The Hanford-67 Series experiments
were conducted on what is now the U.S.
Department of Energy's Hanford site.
Hanford is located in a 40-km-wide
basin in southeastern Washington State
(latitude 46 deg. 34'N, longitude 119
deg. 36'W, elevation 733 feet). The site
is bordered on the north and east by the
Columbia River and on the west and
south by the Rattlesnake Hills and the
Yakima River. The climate of the region
is semiarid. The experiments were con-
ducted on the relatively flat Hanford Dis-
persion Grid at an elevation of roughly
200 m above sea level. The vegetation
on the grid is composed primarily of
steppe grasses and sagebrush. A typical
roughness length for the area is 3 cm.
Four different tracers were released
during the Hanford-67 Series. The par-
ticulate tracers used in the Hanford-67
Series were zinc sulfide fluorescent
particulate 2210, fluorescein, and
rhodamine B. The fourth tracer was
krypton-85, an inert gas whose radioac-
tivity could be monitored.
To determine concentrations, the
three particulate tracers were collected
on membrane filters for subsequent
laboratory analysis. Krypton-85 was
monitored using Geiger-Muller tubes.
During the period 1959 to 1973, more
than 300 atmospheric field diffusion ex-
periments were conducted at the Han-
ford reservation near Richland, Wash-
ington. This volume documents 103 of
the more recent of these experiments.
Both diffusion and current meteorologi-
cal data are presented in user-oriented
format.
The reported data include data for
both unstable and stable atmospheric
conditions. Tracer concentrations nor-
malized by dividing by the release rate
are provided on a series of progres-
sively more distant surface arcs. In
some tests, vertical profiles of normal-
ized tracer concentrations are given. A
table for each set of concentration data
contains the run name, tracer name,
date, start time and stop time, release
height, arc distance, and wind speed at
(or near) the release height. Following
the concentration tables, meteorologi-
cal data are given. These meteorologi-
cal tables contain vertical profiles of
temperature, wind speed, wind direc-
tion, and wind direction standard devia-
tion over the time of release for each
test.
