High Altitude Sampling Program

Project Description
The High-Altitude Sampling Program (HASP) database provides
information on EML's archived stratospheric air filter samples
and sample measurements. The HASP program was first established
in 1957 to track the global dispersion of radioactive debris
resulting from atmospheric nuclear testing. Stratospheric air
filter samples and gas samples were collected at several
locations in North and South America and analyzed for nuclear
debris/trace gases.

The database includes several sets of information about archived
samples and data. The High-Altitude Balloon Sampling Program,
Project Ashcan, ran from 1956 to 1983. This program used large
polyethylene balloons to collect samples at altitudes from 20-27
km. The Stardust program used WU-2, RB-57F, RB-57C, and C-130
aircraft to collect samples at altitudes of 6-19 km, and ran
from 1961 through 1967. However, there were earlier aircraft
samples also collected (1957-1961), which were simply called the
High-Altitude Sampling Program at the time, and which are
treated here as belonging to Project Stardust due to
similarities in collection and analysis procedures. In 1967, the
aircraft sampling continued under the Airstream program, which
was discontinued in 1983.
