Application of a rocket-borne UV radiometer onboard KSR-III for O3 measurements

다국어 초록 (Multilingual Abstract)

KSR-III, the third Korean Sounding Rocket, was launched successfully at Anheung, Korea on
Nov. 28, 2002. One of the scientic missions of KSR-III was to measure the stratospheric ozone
density prole by using an onboard four-channel UV radiometer. The apogee of the rocket was
42.8 km, and the total
ight time was 231 s. The UV radiometer onboard the KSR-III measured
the attenuation of solar radiation during ascending phase to obtain a vertical prole of the ozone
density. The detector has UV channels centered at 255, 290, and 310 nm and a visible channel
at 450 nm for attitude reference. Because the measurement of the solar radiation depends on the
response function of the sensor, calibrations of interference lters and phototubes must be done.
The optical calibration system consists of a monochromator, an optical power meter, light detectors,
standard light sources, a control PC, and data acquisition software. The application of the rocketborne
UV radiometer onboard the KSR-III to the ozone measurement are presented together with
the calibration results from the integrated calibration system at the Korea Aerospace Research
Institute. Using the calibration results and the in-situ measurement data, we obtained the ozone
number density prole, and compared with other measurements.
