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 ...

Advances in Diode-Laser-Based Water Vapor Differential Absorption Lidar

EPJ Web of Conferences, 2016
An advanced diode-laser-based water vapor differential absorption lidar (WV-DIAL) has been developed. The next generation design was built on the success of previous diode-laser-based prototypes and enables accurate measurement of water vapor closer to ...

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.

First Steps of Maturation Towards Space of Nested Cavity Optical Parametric Oscillator and Amplifiers for DIAL Based on Periodically Poled Nonlinear Materials [PDF]

EPJ Web of Conferences, 2020
We report on the first steps of maturation towards space of a nested cavity optical parametric oscillator and amplifiers, based on periodically poled nonlinear materials, emitting in the 2µm range for multi species differential absorption lidar (DIAL).

Field tests of the mobile lidar for tropospheric ozone sensing on horizontal (inclined) and vertical paths [PDF]

E3S Web of Conferences
The results of field tests of the mobile lidar for ozone sensing on horizontal (inclined) and vertical paths are presented. The lidar operates on the basis of the differential absorption and scattering method at wavelengths of 299/341 nm and allows ...

Latent Heat Flux Profiles from Collocated Airborne Water Vapor and Wind Lidars during IHOP_2002 [PDF]

, 2007
Latent heat flux profiles in the convective boundary layer (CBL) are obtained for the first time with the combination of the DLR water vapor differential absorption lidar (DIAL) and the NOAA high resolution Doppler wind lidar (HRDL).

Chemical observations of a polar vortex intrusion [PDF]

, 2006
An intrusion of vortex edge air into the interior of the Arctic polar vortex was observed on the 31 January 2005 flight of the NASA DC-8 aircraft. This intrusion was identified as anomalously high values of ozone by Airborne Raman Ozone, Temperature, and
