The measurement campaign at Kiruna (67.84N, 20.41E, 425 m MSL), Sweden, in 1998 lasted from 26 January to 03 April and spectra of the stratospheric trace gases ClO, O3 and N2O in the frequency range from 268 GHz to 279 GHz were measured. The inversion was performed with modified Tikhonov-Phillips-Regularization and Optimal Estimation Method. In the following a selection of spectra and inverted profiles is presented.
