Measurement of an isosbestic point in the Raman spectrum of liquid water by use of a backscattering geometry.
Measurements presented here confirm that a temperature-insensitive point occurs in the backscattered Raman spectrum from liquid water. This result, coupled with existing laboratory measurements of Raman scattering from liquid droplets, indicates that a Raman lidar measurement of cloud liquid water is feasible.
