A new atmospheric boundary layer Raman lidar has been designed and built at EPFL. Temperature and humidity
can be measured out to 500 m at 1 m spatial resolution, 1 s temporal resolution. A unique multi-telescope
design along with 3 nanoseconds 100 Hz pulsed laser operating at 266 nm (in the solar blind region) with ozone
correction allows for nearly constant signal to noise, daytime operation and measurement scales of interest in
micrometeorology. In this presentation we will detail the underlying principle of this lidar and present new
observations of water and temperature microstructure of the lower atmosphere over complex terrain. First
calibration results, field observations over a vineyard and time series of vertical temperature and humidity profiles
will be presented.
