Upper stratospheric ozone anomalies

Upper stratospheric (35-45km) ozone anomalies for six instruments at northern mid-latitudes (30N–60N). Shown are SAGE I+II (blue, A), SBUV/2 (orange, B), UARS/HALOE (red, C), Odin/SMR (magenta, D), Odin/OSIRIS (black, E), and Envisat/SCIAMACHY (cian, F). Also shown under-laid is the all instrument average (green). Thin black lines indicate the fitted trends before and after 1997.
