- The Sub-Millimetre Radiometer (SMR) on board theOdin satellite has been measuring short-lived strato-spheric species such as chlorine monoxide (ClO) sinceOdin’s launch in 2001. Odin/SMR at its sun-synchronousorbit measures at certain local times observations aroundsunrise and sunset at the equator. Due to the drift ofOdin’s orbit in local solar time and the fact that mea-surements are done at different local times, a correctionis required before a monthly zonal mean climatologycan be calculated and trends of ClO can be evaluated.To deal with this, scaling factors are calculated using aphoto-chemical box model for correction of the mixingratios respective to a reference time. The uncertaintiesand limitations of this method are estimated by checkingthe internal consistency of the results, so that comparingthe scaled a.m. ClO time-series to p.m. scaled time-series should give the same results. We found out thatscaling SMR ClO to the ascending time of MicrowaveLimb Sounder (MLS) as reference at about 1.30 a.m. atthe equator gives better result compared to the scalingClO to MLS descending node at about 1.30. p.m. Thetime series calculated for the morning SMR ClO scaled(to 1.30 a.m.) agrees with the evening ClO scaled.
