Abstract The Atmospheric Boundary Layer (ABL) height is a key parameter in air quality research as well for numerical simulations and forecasts. identification of thermally stable layers, often with radiosondes, has been common approach estimating ABL height, though limited temporal coverage. Remote sensing techniques offer essentially continuous measurements. Nevertheless, retrievals from different methods can vary greatly when compared, which particularly notable topographically complex...
During June 2022 surface air temperatures across most of Europe were above the 1991-2020 average and daily maximum reached over 40 ºC southern (according to Copernicus.eu). Unusually high also in Germany, where heat waves took place with 35 ºC. In Jülich Observatory for Cloud Evolution (JOYCE), these extreme temperature humidity conditions registered. JOYCE combines a rather unique set ground-based remote sensing instruments that provide information about...
<p>The Atmospheric Boundary Layer (ABL) height is a key parameter in air quality research as well order to parametrize numerical simulations and forecasts. The identification of thermally stable layers has been one the most common approaches estimate this height. However, radiosonde's coarse temporal resolution not enough investigate diurnal cycle ABL. Remote sensing overcome problem with high resolution. backscatter retrieved by ceilometers elucidates that aerosols are able...
Experimental lock-release gravity currents are investigated as they propagate downslope over varying synthetic topography. We emulate and investigate the dynamics of thermally driven winds that while interacting with roughness a complex topographic surface. The mixing processes between their surroundings studied Particle Image Velocimetry (PIV), entrainment is quantified. magnitude coefficient shown to increase slope increases. Shadowgraph visualizations qualitatively reproduce this...
