      abstract     = {Abstract. An improved cloud index-based method for the
                      detection of clouds in limb sounder data is presented that
                      exploits the spatial overlap of measurements to more
                      precisely detect the location of (optically thin) clouds. A
                      second method based on a tomographic extinction retrieval is
                      also presented. Using CALIPSO data and a generic advanced
                      infrared limb imaging instrument as example for a synthetic
                      study, the new cloud index method is better in detecting the
                      horizontal cloud extent in comparison to the traditional
                      cloud index and has a reduction of false positive cloud
                      detection events by about 30 $\%.$ The results for the
                      extinction retrieval show even an improvement of 60 $\%.$ In
                      a second step, the extinction retrieval is applied to real
                      3-D measurements of the air-borne limb sounder GLORIA taken
                      during the Wave-driven ISentropic Exchange (WISE) campaign
                      to retrieve small-scale cirrus clouds with high spatial
                      accuracy.},
