Ozone differential absorption lidar algorithm intercomparison

open access: yesApplied Optics, 1999
An intercomparison of ozone differential absorption lidar algorithms was performed in 1996 within the framework of the Network for the Detection of Stratospheric Changes (NDSC) lidar working group. The objective of this research was mainly to test the differentiating techniques used by the various lidar teams involved in the NDSC for the calculation of

Lidar differential absorption and scattering technique: theory

Applied Optics, 1983
The results of theoretical investigations of the differential absorption technique for sounding atmospheric water vapor are described in this paper. The sources of errors and their effect on the results of interpreting the sounding data are analyzed. The mathematical problems for inverting the lidar returns are considered.

Continuous‐wave differential absorption lidar

open access: yesLaser & Photonics Reviews, 2015
AbstractThis work proves the feasibility of a novel concept of differential absorption lidar based on the Scheimpflug principle. The range‐resolved atmospheric backscattering signal of a laser beam is retrieved by employing a tilted linear sensor with a Newtonian telescope, satisfying the Scheimpflug condition.

Coherent differential absorption lidar measurements of CO_2

Applied Optics, 2004
A differential absorption lidar has been built to measure CO2 concentration in the atmosphere. The transmitter is a pulsed single-frequency Ho:Tm:YLF laser at a 2.05-microm wavelength. A coherent heterodyne receiver was used to achieve sensitive detection, with the additional capability for wind profiling by a Doppler technique.
