  1. Stratospheric Temperature Time Series 1/79 to 12/05 J. Nash, R. Lin and A.J. Miller

  2. Tiros, NOAA- 6, 7, 8, 9, 11, 14 - SSUNOAA-15, 16, 17, 18 - AMSUAQUA - AMSU

  3. Data Availability Nash SSU data 1/79-5/98 standardized to NOAA-6 NOAA N-14 data 6/98 – 12/05; overlap Nash 7/95-5/98 to remove bias; not adjusted for semi-diurnal tides NOAA N-11 data 7/97 – 12/03; overlap Nash 7/97-5/98 to remove bias; not adjusted for semi-diurnal tides In addition, overlap N-11 with N-14 2001 to remove bias; not adjusted for semi-diurnal tides AMSU-15 data 7/98 – present * Channel 14 lost 11/00 * Channel 11 lost 5/02 * Data stable to within 0.02C, 1998-2005 *Use 4 channels for entire period * Regressed against N-14 7/98-6/00 to simulate SSU AQUA data 1/03 – present * Regressed against N-14 1/03-12/03 to simulate SSU *Use 6 channels

  5. NOAA N-14 minus NASH N-14

  6. NOAA N-14 minus NASH N-14

  7. NOAA N-11 minus NASH N-14

  8. NOAA N-11 minus NASH N-14

  9. AMSU => SSU via Statistical Regression 14 SSU25, etc = a0 + 3 ai x AMSUi i=9

  10. AMSU N-15 SD of Simulation of N-14 SSU7/98- 6/00

  11. AQUA AMSU SD of Simulation of N-14 SSU1/03- 12/03

  12. Integrated Temperature 70N-70S

  13. Data Availability • The URL for the SSU dataset will be ftp://ftp.cpc.ncep.noaa.gov/wd53rl/ssu/cohesive/
