Comparison of DIAL and Raman techniques
Measuring atmospheric gas with LIDAR

It is instructive to compare the sensitivity of Raman and DIAL lidar measurements, in a common scenario that allows this. To do this, we start again from equations (14) and (29) , which provide the balance equation of a Raman lidar and an RR-DIAL lidar respectively for the distance bin of index k, and we assume a situation where the target gas is present only on the distance bin k, under homogeneous physico-chemical conditions (concentration,...
