Measurement of middle atmospheric ozone density profile by rocket-borne radiometer onboard KSR-II

Abstract

KSR-II, a two-stage sounding rocket of KARI was launched successfully at the Korean Peninsula on June 11, 1998. The apogee of the rocket was 137 km. For the ozone measurement, 8-channel UV and visible radiometers were onboard the rocket. The rocket measured an in situ stratospheric and mesospheric ozone density profile over Korea during its ascending phase using the radiometer and transmitted the data to ground station in real time. The maximum ozone density occurs near 25 kin. Retrieved profile has a random error(1 sigma) of approximately 15% for altitude below 20km, 7% between 20-50 km and 10% greater than 50 kin. The retrieved data were compared with Dobson spectrophotometer, ozonesonde, and HALOE onboard the UARS. Our results are in reasonable agreements with others. (C) 2001 COSPAR.
