Scientific paper

The long-term temperature datasets obtained by Rayleigh lidars at three different locations from low to high latitudes within the Network for the Detection of Atmospheric Composition Change (NDACC) were used to derive the inter-annual variability (e.g. QBO, ENSO, solar cycle) of middle atmosphere temperature: Mauna Loa Observatory, Hawaii (MLO, 19.5°N); Table Mountain Facility, California (TMO, 34.4°N); Observatoire de Haute Provence, France (OHP, 43.9°N). We found that the significant stratospheric QBO oscillation was observed at all three lidar sites with clearly downward phase progression only at MLO. The mesospheric QBO was also observed, but not statistically significant. The significant temperature responses to ENSO were observed to be negative at MLO and TMF and positive at OHP in the stratosphere, while in the middle mesosphere, a significant positive response was found at MLO and small negative was found at OHP, consistent with the results of recent model simulation. In addition, we also revealed the temperature response to 11-year solar cycle and temperature trend in the middle atmosphere. The lidar observed inter-annual variability was compared with the results derived from ECMWF simulation and TIMED/SABER satellite observations, and the general agreements were found.
