Description of the payload
An instrument for atmospheric ozone In Situ measurements.
The photometer's primary components are a mercury lamp, two identical sample chambers, two detectors, and a scrubber. The lamp provides 254 nm radiation that is transmitted through the length of the chambers to the detectors, one chamber containing the air sample with ozone and other containing air with the ozone removed.
Ozone strongly absorbs this wavelength, allowing virtually continuous measurements of ozone by comparing the detected signals in the two chambers, and periodically alternating the roles of the two chambers.
