Autor: I. Cheliotis, E. Dieudonné, H. Delbarre, A. Sokolov, E. Dmitriev, P. Augustin, M. Fourmentin

Publikováno v: Atmospheric Measurement Techniques, Vol 13, Pp 6579-6592 (2020)

Medium-to-large fluctuations and coherent structures (mlf-cs's) can be observed using horizontal scans from single Doppler lidar or radar systems. Despite the ability to detect the structures visually on the images, this method would be time-consumin

Due to the major role of the sun in heating the earth's surface, the atmospheric planetary boundary layer over land is inherently marked by a diurnal cycle. The afternoon transition, the period of the day that connects the daytime dry convective boun

Publikováno v: Natural Hazards and Earth System Sciences, Vol 14, Iss 3, Pp 509-523 (2014)

Vegetation fires emit large amount of gases and aerosols which are detrimental to human health. Smoke exposure near and downwind of fires depends on the fire propagation, the atmospheric circulations and the burnt vegetation. A better knowledge of th
