Verification of cloudiness and radiation forecasts in the greater Alpine region

Meteorologische Zeitschrift, 2016
The skill of ECMWF operational cloudiness and radiation forecasts is evaluated for the greater Alpine region using ground-based and satellite observations. Ground-based observations are the total cloud cover reported by SYNOP stations. The satellite data

Applying deep learning to NASA MODIS data to create a community record of marine low-cloud mesoscale morphology [PDF]

Atmospheric Measurement Techniques, 2020
Marine low clouds display rich mesoscale morphological types and distinct spatial patterns of cloud fields. Being able to differentiate low-cloud morphology offers a tool for the research community to go one step beyond bulk cloud statistics such as ...

Re‐Evaluation of Low Cloud Amount Relationships With Lower‐Tropospheric Stability and Estimated Inversion Strength

Geophysical Research Letters, 2022
Lower‐tropospheric stability (LTS) and estimated inversion strength (EIS) have a widely accepted relationship with low cloud amount and are key observational foundations for understanding and modeling low‐level stratiform clouds.

The PreVOCA experiment: modeling the lower troposphere in the Southeast Pacific [PDF]

Atmospheric Chemistry and Physics, 2010
The Preliminary VOCALS Model Assessment (PreVOCA) aims to assess contemporary atmospheric modeling of the subtropical South East Pacific, with a particular focus on the clouds and the marine boundary layer (MBL). Models results from fourteen modeling

Advances in Predicting Continental Low Stratus with a Regional NWP Model

Weather and Forecasting, 2010
Abstract In the eastern Alpine region, subinversion cloudiness associated with elevated temperature inversions is a frequent phenomenon in autumn and winter, which often persists for several days. Although the prediction of fog and low stratus by numerical weather prediction (NWP) models has improved in recent years, these models still ...

A Case Study on Fog/Low Stratus Occurrence at Las Lomitas, Atacama Desert (Chile) as a Water Source for Biological Soil Crusts

Aerosol and Air Quality Research, 2018
The Atacama Desert is well known for the high occurrence of large-scale fog (spatial extents: hundreds of kilometers) emerging as low stratus (LST) decks over the Pacific Ocean. By contrast, the small-scale and heterogeneous occurrence of small-scale fog
