We present the design of a new instrument that combines Raman spectroscopy and linear polarization analysis to identify the fraction of ice, liquid and water vapor in tropospheric aerosols and cloud layers.

In this case water and ice fractions are obtained using the Raman N2 line as reference. The instrument also measures the polarimetric S and P state of the backscattering lidar signal.

In this article an overview of the scientific applications of this instrument is given followed by a theoretical estimation of the lidar returns as well as the instrumental concept and design.

First light of lidar profiles will be provided during conference.
