Presentation transcript:

Some analyses of updated SSU data –merging Nash data with NOAA-11 and NOAA-14 –derived trends, solar cycle –comparisons with NCEP/ERA40/HALOE data

SSU: ~10-15 km thick layer temperatures

data from NOAA operational satellites

NOAA-11 NOAA-14 note flattening of trends since ~1995 small long-term cooling in middle strat.

MSU4 trends

SSU15x trends NOAA-14NOAA-11

NOAA-14 Annual average trends

Model vs. observed trends ( ) Shine et al., 2003 x trends

How do we interpret stratopause variability? ? ~45-60 km

How do we interpret stratopause variability? ? ~45-60 km

Model vs. observed trends ( ) Shine et al., 2003 x trends x why are middle stratosphere trends so small ?

Seasonal trends (N11)

SSU vs. HALOE SSU 27 ~35-50 km HALOE integrated to approximate SSU 27

SSU vs. HALOE SSU 47x ~43-57 km HALOE integrated to approximate SSU 47x

Problems in operational analyses / reanalyses due to changes in satellite instruments vertically integrated to approximate SSU 36x (~35-50 km)

Global mean 100 hPa temps from analyses / reanalyses Note spurious changes due to evolution of data / analysis systems TOVS – ATOVS change each data set normed to zero for

Temperature solar cycle NOAA-11 NOAA-14

Observations vs. model FUB model, Matthes et al., 2004

Observed ozone and temp changes 40 km ozone km temperature note coherent variability (temperatures respond to ozone)

Some key points: Significant differences between updated record using NOAA-11 and NOAA-14 data Strong upper stratosphere cooling ends after ~1995 (reasonable agreement with HALOE data) No significant trends in tropical lower stratosphere in MSU4 and SSU15x data (very different from radiosondes) Small global trends in middle stratosphere (different from models) Reanalysis data sets problematic for trends Solar cycle ~1 K, maximizes in tropical middle-upper stratosphere
