A new high spatial resolution low stratus/fog retrieval for the Atacama Desert
Remote Sensing of Environment, 2020Abstract The Atacama Desert is considered as one of the driest places on Earth. At the coastline, however, small-scale fog oases harbor a specialized vegetation and fauna, living from moisture by fog, which is used by humans to feed water demands of industrial projects.

Unified Low Stratus Cloud-Subcloud Microphysics Model
SPIE Proceedings, 1989Thermodynamics, turbulence, and dynamics of damp, saturated and supersaturated air are systematically considered to produce a unified low stratus cloud-subcloud microphysics model. The model produces vertical profiles of temperature, pressure, density, specific humidity, relative humidity, liquid water content, drop size distributions, wind and ...

Aircraft icing in visual meterological conditions below low stratus clouds
Atmospheric Research, 1995Abstract There are many reports about icing slightly below stratus clouds in visual meteorological conditions (VMC), which obviously occurs very often but not only in polar regions and over the sea. Calculations of the ice shape at the leading edge of aircraft wings and the main rotor blades of helicopters by computers of GMGO (German Military ...

A satellite perspective on fog and low stratus dissipation over Europe
2021<p>In this study, the dissipation of fog and low stratus (FLS) over Europe is analyzed based on geostationary satellite data using logistic regression.&#160;<br>The dissipation of FLS is a result of the interaction of complex physical processes and its timing has implications for environmental systems, traffic at ...

Low stratus at Embakasi Airport Nairobi
pure and applied geophysics, 1971The relatively frequent occurrence of low cloud in the area of Embakasi Airport near Nairobi (Kenya) is a great hazard particularly to aircraft without automatic landing device. The desire was therefore that the flight direction and control staff receive early and reliable information of low cloud from the meteorologist. The great difficulty is evident

Model For Estimating Vertical Extinction Profiles In Low Stratus Subclouds
SPIE Proceedings, 1988A microphysical model is presented which can be used to provide first approximations of vertical extinction profiles for low stratus subclouds. The thermodynamic portion of the model is based on particle growth models by Hanel, drop-size distributions by Duncan and Low, or Shettle and Fenn, bulk phase change thermodynamics, and a mass balance ...

Fog and low stratus over the Swiss Plateau − a climatological study
International Journal of Climatology, 2013ABSTRACTThe occurrence of fog and low stratus (FLS) clouds is a common phenomenon over the Swiss plateau during the winter half years. Classical fog observations using horizontal visibility are of limited use for climatological analyses of persistent FLS situations.

Fog - low stratus (FLS) regimes on Corsica with wind and PBLH as key drivers
Atmospheric Research, 2021Abstract The French Mediterranean island of Corsica is already today confronted with a clear tendency towards water shortage, leading not only to socio-economical, but also to ecological problems. A potential, but not very widespread source of water is the presence of near-ground clouds, mostly fog. In this study, we investigate fog-low stratus (FLS)

A novel approach to fog/low stratus detection using Meteosat 8 data
Atmospheric Research, 2008A method is presented for fog and low stratus detection from daytime satellite imagery based on Meteosat 8 SEVIRI (Spinning-Enhanced Visible and Infra-Red Imager) data. With its excellent spatial, spectral and temporal resolutions, this imagery is an ideal basis for operational fog monitoring. The scheme utilizes a range of pixel-based and novel object-
