Stabilized master laser system for differential absorption lidar [PDF]

Applied Optics, 2010
Wavelength accuracy and stability are key requirements for differential absorption lidar (DIAL). We present a control and timing design for the dual-stabilized cw master lasers in a pulsed master-oscillator power-amplifier configuration, which forms a robust low-cost water-vapor DIAL transmitter system.

Intercomparison of Water Vapor Data Measured with Lidar during IHOP_2002. Part II: Airborne-to-Airborne Systems [PDF]

, 2007
The dataset of the International H2O Project (IHOP_2002) gives the first opportunity for direct intercomparisons of airborne water vapor lidar systems and allows very important conclusions to be drawn for future field campaigns.

Local-Scale Horizontal CO₂ Flux Estimation Incorporating Differential Absorption Lidar and Coherent Doppler Wind Lidar

Remote Sensing, 2022
A micro-pulse lidar system incorporating differential absorption lidar (DIAL) and coherent Doppler wind lidar (CDWL) is proposed and demonstrated. Due to the high signal-to-noise ratio (SNR) of the superconducting nanowire single-photon detector (SNSPD),

Development of water vapor DIAL and comparison with Raman lidar [PDF]

EPJ Web of Conferences
Vertical profile measurements of water vapor are important for improving early prediction accuracy of heavy rainfall. Developing a low-maintenance lidar is expected to establish an extensive lidar observation network to reduce water-related hazards such ...

Imaging of Atmospheric Dispersion Processes with Differential Absorption Lidar [PDF]

SIAM Journal on Imaging Sciences
We consider the inverse problem of fitting atmospheric dispersion parameters based on time-resolved back-scattered differential absorption Lidar (DIAL) measurements. The obvious advantage of light-based remote sensing modalities is their extended spatial range which makes them less sensitive to strictly local perturbations/modelling errors or the ...

Differential Absorption Lidar (DIAL) Measurements of Landfill Methane Emissions

Remote Sensing, 2017
Methane is one of the most important gaseous hydrocarbon species for both industrial and environmental reasons. Understanding and quantifying methane emissions to atmosphere is therefore an important element of climate change research.
