<abstract>
<p>The long term evolution of stratospheric ozone and water vapour has
been investigated by extending satellite time series to April 2008. For ozone, we examine monthly average ozone values from various
satellite data sets for nine latitude and altitude bins covering
60&amp;deg; S to 60&amp;deg; N and 20–45 km and
covering the time period 1979–2008. Data are from the Stratospheric
Aerosol and Gas Experiment (SAGE I+II), the HALogen Occultation
Experiment (HALOE), the Solar BackscatterUltraViolet-2 (SBUV/2)
instrument, the Sub-Millimetre Radiometer (SMR), the Optical
Spectrograph InfraRed Imager System (OSIRIS), and the SCanning Imaging
Absorption spectroMeter for Atmospheric CHartograpY
(SCIAMACHY). Monthly ozone anomalies are calculated by utilising
a linear regression model, which also models the solar, quasi-biennial
oscillation (QBO), and seasonal cycle contributions. Individual
instrument ozone anomalies are combined producing a weighted all
instrument average. Assuming a turning point of 1997 and that the all
instrument average is represented by good instrumental long term
stability, the largest statistically significant ozone declines from
1979–1997 are seen at the mid-latitudes between 35 and 45 km,
namely &amp;minus;7.7%/decade in the Northern Hemisphere and &amp;minus;7.8%/decade
in the Southern Hemisphere. For the period 1997 to 2008 we find that
the southern mid-latitudes between 35 and 45 km show the
largest ozone recovery (+3.4%/decade) compared to other global
regions, although the estimated trend model error is of a similar
magnitude (+2.1%/decade, at the 95% confidence level). An all
instrument average is also constructed from water vapour anomalies
during 1984–2008, using the SAGE II, HALOE, SMR, and the Microwave
Limb Sounder (aura/MLS) measurements. We report that the decrease in
water vapour values after 2001 slows down around 2004 in the lower
tropical stratosphere (20–25 km), and has even shown signs of
increasing values in upper stratospheric mid-latitudes. We show that
a similar correlation is also seen with the temperature measured at
100 hPa during this same period.</p>
