A laboratory pre-prototype of an optical ozonesonde will be
designed, built, and tested for disposable, balloon-borne sounding
of the stratosphere and troposphere. The device will use short-
path UV absorption and high-precision signal processing circuitry
to enable high-sensitivity, absolute determinations of ozone
concentrations from the ground to 40 km. The laboratory tests will
evaluate the instrument sensitivity, thermal stability, and
operating characteristics upon exposure to low pressures and
temperatures. The end result of Phase I will be a working design
of prototype flight instruments to be built and flown in Phase II.
The eventual flight instrument will be superior to current
disposable sonde technology because it will be much easier to
implement in the field, will provide higher altitude coverage for
satellite validation, and will provide accurate absolute ozone
determinations without the need for ground-based corroborations.
The instrument can be used reliably at any accessible location,
and will provide previously unavailable sounding capabilities for
determinations of ozone depletion in the high-latitude polar

Potential Commercial Applications: The optical ozonesonde has
commercial applications for worldwide atmospheric monitoring
networks for tropospheric ozone and climatology research.
