Fog and low-level stratus characteristics at the airport of Odesa from surface observations [PDF]

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія, 2023
Introduction. Fog that limits visibility and low-level stratus represent a significant hazard to aviation especially during takeoff and landing, and also low-level flying of aircrafts, because accidents often occur in reduced visibility conditions and ...

1 km fog and low stratus detection using pan-sharpened MSG SEVIRI data [PDF]

open access: yesAtmospheric Measurement Techniques, 2012
In this paper a new technique for the detection of fog and low stratus in 1 km resolution from MSG SEVIRI data is presented. The method relies on the pan-sharpening of 3 km narrow-band channels using the 1 km high-resolution visible (HRV) channel.

Advanced Dual-Satellite Method for Detection of Low Stratus and Fog near Japan at Dawn from FY-4A and Himawari-8

open access: yesRemote Sensing, 2021
The detection of low stratus and fog (LSF) at dawn remains limited because of their optical features and weak solar radiation. LSF could be better identified by simultaneous observations of two geostationary satellites from different viewing angles.

Automatic Detection of Daytime Sea Fog Based on Supervised Classification Techniques for FY-3D Satellite

open access: yesRemote Sensing, 2023
Polar-orbiting satellites have been widely used for detecting sea fog because of their wide coverage and high spatial and spectral resolution. FengYun-3D (FY-3D) is a Chinese satellite that provides global sea fog observation.

Quantifying Parametric Uncertainty Effects on Tropical Cloud Fraction in an AGCM

open access: yesJournal of Advances in Modeling Earth Systems, 2023
The underestimation of cloud fraction, especially the low stratus cloud (LSC) fraction over the eastern oceans, remains a problem in most atmospheric global climate models.

What controls the formation of nocturnal low-level stratus clouds over southern West Africa during the monsoon season? [PDF]

open access: yesAtmospheric Chemistry and Physics, 2019
Nocturnal low-level stratus clouds (LLCs) are frequently observed in the atmospheric boundary layer (ABL) over southern West Africa (SWA) during the summer monsoon season.

A Locally Smoothed Terrain‐Following Vertical Coordinate to Improve the Simulation of Fog and Low Stratus in Numerical Weather Prediction Models

open access: yesJournal of Advances in Modeling Earth Systems, 2021
The correct simulation of fog and low stratus (FLS) is a difficult task for numerical weather prediction (NWP) models. The Swiss Plateau experiences many days with FLS in winter. Most NWP models employ terrain‐following vertical coordinates.

Characteristics of Aerosol and Cloud over the Central Plain of North China in Summer

open access: yes应用气象学报, 2021
The vertical distribution of aerosols and clouds is a key issue in the indirect climate effects of aerosols. Based on the aerosol and cloud droplet number concentration data observed by 6 aircrafts over the central plain of North China from July to ...
