NSKY-CD: A System for Cloud Detection Based on Night Sky Brightness and Sky Temperature

open access: yesRemote Sensing, 2023
Cloud cover is important meteorological information that still requires expensive equipment to be monitored from the ground, especially at night. The use of artificial lights at night causes light pollution, and clouds amplify this by reflecting light ...
