                   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

                 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.
