Lidar Calibration Centre LICAL

LIDAR CALIBRATION CENTER

Lidar is not a “push button” device. Even if fully automatic, it requires supervision because its calibration may change with time and environmental conditions. The quality of the final data products depends crucially on the performance of the instrument, operator’s skills and experience, and data handling procedures.Therefore, lidar calibration is a complex process, relying on the quantitative assessment of the instrument’s performance and its continuous control.

Complementary laboratory

Complementary laboratory includes two meteorological stations for temperature, pressure, relative humidity, wind speed and wind direction. Measured data are compared with forecasted data, by use of the regional model MAP3D, to investigate the contribution of distributed pollution sources to the...

In situ analysis laboratory

In situ analysis laboratory includes an aerosol mass spectrometer, optical and gravimetric particle counters, a particle size spectrometer, a three color integrating nephelometer, 33-gaseous compounds differential optical absorption spectroscopy system and point monitors for O3, SO2, NOx and HC...

Passive remote sensing laboratory

Passive Remote sensing laboratory includes 2 microwave radiometers, solar and lunar sunphotometer, razon+ and real time satellite images through Eumetcast. Profiles of temperature and humidity are correlated with lidars data, as well as AERONET sunphotometer derived information.

Active remote sensing laboratory

The Active Remote Sensing laboratory includes five lidar systems (multi-wavelength Raman, eye-safe scanning mobile UV mini-lidar, ozone, fluorescence) and a sodar. These instruments provide profiles of aerosol, ozone and organic matter, optical parameters and wind speed and direction. Optical...
