abstract = "The characteristics of low-frequency interannual changes in stratospheric constituents are examined using measurements from the HALOE [1991-1999] and SAGE II [1984-1998] satellite instruments. Both the increasing H2O and decreasing CH4 observations from the first several years of HALOE measurements are found to be absent (or partially reversed) in the data since \textasciitilde{} 1996. Ozone and NOx (NO + NO2) observations from HALOE also show 'trends' over \textasciitilde{} 1991-1995 that become flat in the latter record. Comparisons with the longer-term SAGE II measurements of ozone and NO2 demonstrate that changes over the short period 1991-1995 are not representative of decadal-scale trends, but rather are episodic in nature. One possibility is that these changes reflect a prolonged response to the Mt. Pinatubo volcanic eruption in 1991. Stratospheric temperatures and derived circulation statistics are examined for the period 1979-1999. While Pinatubo produced enhanced tropical upwelling in the stratosphere for 1-2 years, other sources of stratospheric variability probably also contribute to low-frequency constituent 'trends.'",
