Short summary

The comparison of observations performed by different techniques and satellite instruments is important. An intercomparison of the stratospheric NO₂ derived from ground-based and satellite instruments has been carried out over the Izaña subtropical site. The importance of the use of the effective solar zenith angle when comparing noon measurements with twilight measurements of photochemically active species is highlighted. All instruments show positive trends in NO₂ stratospheric column.
