Global estimation of range resolved thermodynamic profiles from micropulse differential absorption lidar. [PDF]

Optics Express
We demonstrate thermodynamic profile estimation with data obtained using the MicroPulse DIAL such that the retrieval is entirely self contained. The only external input is surface meteorological variables obtained from a weather station installed on the ...

Tropospheric NO2 Measurements Using a Three-wavelength Optical Parametric Oscillator Differential Absorption Lidar

Atmospheric Measurement Techniques, 2021
. The conventional two-wavelength Differential Absorption Lidar (DIAL) has measured air pollutants such as nitrogen dioxide (NO2). However, high concentrations of aerosol within the planetary boundary layer (PBL) can cause significant retrieval errors ...

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.
