REAL  is an elastic Raman LIDAR system specially developed by ALA to provide a wealth of information about the atmosphere by paying specific attention to aerosol loading in a very large range of altitude from 200m to 30km.

REAL detects the signal by using both the analogical and the photo-counting detection, combining the weak signal from high altitude with the strong one from lower altitude.

REAL has a manual swivelling system that allows pointing the laser beam; the system combines high research performance with portability, friendliness and compactness.
