2. Major Elements Total Ozone: SBUV/(/2) 1979-2004 Temperature Profiles: SSU 1979-2004 Temperature: MSU(4) 1979-2004 Question: In an atmosphere where ozone is recovering and CO2 increasing, how do we separate temperature impacts?

8. Channel 25 Instruments generally match within about 0.3 radiance units Exception is NOAA-9 which is about 0.5 radiance unit higher than others

9. Channel 26 Instruments generally match within 2 radiance units Exception is NOAA-7 which is about 3 radiance units high

10. Channel 27 Spectroscopic and tidal effects dominate General agreement between instruments of about 3 radiance units in equatorial region, increasing to about 5 radiance units in polar latitudes
