This topical issue of the Journal of Pure and Applied Geophysics (PAAG) on ice fog, ice clouds, and remote sensing focuses on cold fog and ice cloud microphysics and dynamics in earth¿s boundary layer. The measurements from state of art in-situ instruments, remote sensing platforms, and simulation results from numerical weather prediction (NWP) models are used in this book.

Use of remote sensing platforms, including satellites, radiometers, ceilometers, sodars, and lidars, as well as in-situ sensors for the monitoring, and short term forecasting of cold fog and ice clouds are required to improve present knowledge. The new scientific challenges in addition to present knowledge on cold fog and ice clouds are also considered. University students, postgraduates, and researchers interested in cold fog and ice clouds, related to forecasting and nowcasting, aviation meteorology, remote sensing, climate, hydrometeorology, and agriculture meteorology can benefit extensively from this topical issue.
