The ENEA Atmospheric Lidar is one of the systems of the Laser Remote Sensing Mobile Laboratory under development at the ENEA Research Center of Frascati. Its main objective is to monitor the urban pollution according to the European Union guidelines. In particular, the load of aerosols and the concentration of [Java Applet] and [Java Applet] will be profiled. In order to achieve this purpose, a double spectral range scheme has been chosen, which combines the advantages of ultraviolet-visible (UV-VIS) and infrared (IR) bands, thanks to the simultaneous operation of two lidars. The UV-VIS transmitter is based on a Nd:YAG pumped dye laser (with or without frequency doubling crystals for UV or VIS generation, respectively). The IR transmitter is based on a TEA [Java Applet] laser. Each receiver includes a coelostat (system of two scanning mirrors) to sweep the complete hemisphere while avoiding transmitter-receiver misalignments.
