| Zusammenfassung |
| A ground-based Rayleigh lidar has provided continuous observations of
tropospheric water vapour profiles and cirrus cloud using a preliminary Raman
channels setup on an existing Rayleigh lidar above La Reunion over the
period 2002–2005. With this instrument, we performed a first measurement
campaign of 350 independent water vapour profiles. A statistical study of the
distribution of water vapour profiles is presented and some investigations
concerning the calibration are discussed. Analysis regarding the cirrus
clouds is presented and a classification has been performed showing 3
distinct classes. Based on these results, the characteristics and the design
of a future lidar system, to be implemented at the new Reunion Island
altitude observatory (2200 m) for long-term monitoring, is presented and
numerical simulations of system performance have been realised to compare
both instruments. |
