Is it true that LIDAR works in fog or rain?
Partly. Several peer-reviewed studies report that LiDAR detection performance is reduced or degraded in rain and fog, while one laboratory study reports that LIDAR-based weather recognition works adequately in rain and fog. The evidence addresses degraded performance rather than whether LiDAR functions at all in those conditions.
