Abstract. The Halogen Occultation Experiment (HALOE) on board the Upper Atmosphere research satellite (UARS) has observed mixing ratios of important trace species in the stratosphere over more than a decade since 1991. Here we present a climatology for the stratosphere compiled from the HALOE data for ozone, H2O and CH4 for the period from 1991 to 2002. In this approach, the data are averaged over equivalent latitude instead of latitude in order to correctly reproduce the gradients at the transport barriers like the polar vortex edge. The climatology is compiled for 5 degree equivalent latitude bins. The seasonal dependence is taken into account by choosing intervals of one month. The climatology is available as an electronic supplement.
