Abstract
We assess the feasibility of correcting the aerosol optical depth by measuring an overlap function from the combination of elastic and N2/O2 rotational-spectrum Raman signals in an advanced aerosol lidar. It is shown that very similar overlap functions can be derived from measurements taken in different days, leading to an extension of minimum range at which the aerosol optical depth can be measured. This opens the way to determining the aerosol extinction coefficient at ranges below the lidar full overlap with overlap functions measured in favorable conditions.
