Research on Synchronous Inversion Algorithm Based on Tri-Wavelength DIAL
OpticsTraditionally, retrieving both temperature and CO2 concentration in atmospheric remote sensing has relied on two independent lidar systems, leading to increased system complexity and limited coordination.

Latent Heat Fluxes over Complex Terrain from Airborne Water Vapour and Wind Lidars [PDF]
, 2009 Tropospheric profiles of water vapour and wind were measured with a differential absorption lidar (DIAL) and a heterodyne detection Doppler wind lidar collo-cated onboard the DLR Falcon research aircraft in the past two years.

Increasing urban flash flood risk attributable to both climate and development
Quarterly Journal of the Royal Meteorological Society, EarlyView.A new event impact attribution methodology that combines convection‐permitting climate model data with flood inundation modelling was used for a five‐hour flash‐flooding event in the suburbs of Leeds in 2014. The results show increased urban flood extent due to both climate change (+16%) and increased urbanisation (+29%).

Latent Heat Fluxes over Complex Terrain Measured by Airborne Water Vapour and Wind Lidars [PDF]
, 2010 The combination of a water vapour and a wind lidar on an aircraft is an interesting new tool that allows to measure latent heat flux profiles and to portray the small- to mesoscale variability beneath the aircraft trajectory with high accuracy and ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates the thermodynamic and microphysical characteristics of updrafts and downdrafts of tropical deep convective anvil clouds using in situ measurements. We found that parts of the downdrafts are in ice supersaturation in these clouds.

Progressive emergence of canopy gravity waves during the afternoon–evening transition
Quarterly Journal of the Royal Meteorological Society, EarlyView.Large‐eddy simulations are used to investigate the afternoon‐to‐evening transition of turbulence over a forest canopy and its coupling with atmospheric boundary‐layer dynamics. As surface cooling strengthens stability and weakens near‐canopy winds, canopy turbulence transitions progressively to internal gravity waves that dominate the evening flow ...

EPJ Web of Conferences, 2018 Monitoring the emission of gases is difficult to achieve in industrial sites and in environments presenting poor infrastructures. Hence, robust methodologies should be developed and coupled to Lidar technology to allow remote sensing of gas emission ...

Scheimpflug-like processing of differential absorption lidar data on water vapor [PDF]
EPJ Web of ConferencesDifferential Absorption Lidar (DiAL) method is widely used for a number of ground-based and airborne greenhouse gas measurement applications. However, for a direct detection in the 2µm range, other sources of random noise can be neglected in front of the
