ALICEnet (Automated LIdar-CEilometer network) is an operational network of automated lidar-ceilometers (ALC) run by Italian research institutions and environmental agencies aimed at improving and promoting the multi-disciplinary use of environmental data. ALICEnet provides near-real-time aerosol and clouds profiling by several ALCs located across Italy.

ALC profiles allow to derive the following information:

  • Mixing layer height (pollutants dispersion height);
  • Time-altitude distribution of particulate matter;
  • Presence and concentration of Saharan/fires/volcanic plumes;
  • Cloud height;
  • Fog level;

This information is useful in the fields of meteorology, air quality, environmental monitoring and flight safety as well as for radiative and climate studies. Posted data are preliminary and their copyright belongs to the station PIs.
