Lidar method for measuring atmospheric and environmental variables

摘要

The method measures variables including temperature, pressure, humidity, wind speeds, cloud heights, and the presence of aerosols or other atmospheric pollutants. For these determinations a light source projects a beam, whose linear/non-linear returned scatter, brought about by particles from atomic size upwards, is registered and evaluated by the lidar system or its variants. During the programme of data collection and evaluation, the necessary equipment is carried by a land vehicle running freely or a train running on tracks.
