We discuss 223 middle atmosphere lidartemperature observations. The record was collected at Frascati (42°N–13°E),during the 41-month period January 1989-May 1992, corresponding to the maximumof solar cycle 22. The choice of this interval was aimed at minimizing thetemperature variability induced by the 11-year solar cycle. The averageclimatology 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 byvariability caused by the natural phenomena considered in the analysis. Due tothis minimum in natural noise characterizing the atmospheric temperature justabove the stratopause, observations of that region are well suited to thedetection of possible temperature trends induced by industrial activities
