Remote measurement of atmospheric mercury using differential absorption lidar [PDF]

open access: yesOptics Letters, 1982
Atomic mercury in the atmosphere was detected by the differential-absorption lidar technique. Laser light at the mercury resonance wavelength of 253.65 nm was generated by anti-Stokes shifting in H(2) of the frequency-doubled output from a Nd:YAG-pumped dye laser.

Measuring Water Vapor with Differential Absorption Lidar

open access: yes, 2012
Despite the need for global measurements of water vapor profiles with low bias and high vertical resolution there is currently no operational remote sensing system that would deliver such data. A possible solution to this problem is offered by the differential absorption lidar (DIAL) approach. The basic principle of operation will be described and some
