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 ...

Remote Sensing in Ecology and Conservation, EarlyView.This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

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.

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

Human Recreation and Fire History Shape Landscape Connectivity for an Endangered Forest Carnivore
Animal Conservation, EarlyView.Roads and trails can impede wildlife movement, but their permeability varies with human use and fire history. We combined GPS telemetry from 45 endangered southern Sierra Nevada fishers (Pekania pennanti) with smartphone‐derived human mobility data to estimate crossing probability across road and trail segments. Fishers were about 2.5 times more likely

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 ...

Feasibility Study of Multi-Wavelength Differential Absorption LIDAR for CO2 Monitoring
Atmosphere, 2016 To obtain a better understanding of carbon cycle and accurate climate prediction models, highly accurate and temporal resolution observation of atmospheric CO2 is necessary. Differential absorption LIDAR (DIAL) remote sensing is a promising technology to
