| Zusammenfassung |
| We discuss 223 middle atmosphere lidar
temperature observations. The record was collected at Frascati (42°N–13°E),
during the 41-month period January 1989-May 1992, corresponding to the maximum
of solar cycle 22. The choice of this interval was aimed at minimizing the
temperature variability induced by the 11-year solar cycle. The average
climatology over the 41-month period and comparison with a reference atmosphere
(CIRA86) are presented. Monthly temperature variability over the full period,
during opposite quasi-biennial oscillation phases and on a short-term scale
(0.5–4 h), is analyzed. Results indicate the 50–55-km region as less affected by
variability caused by the natural phenomena considered in the analysis. Due to
this minimum in natural noise characterizing the atmospheric temperature just
above the stratopause, observations of that region are well suited to the
detection of possible temperature trends induced by industrial activities. |
