Aircraft use RADAR for weather detection such as storm clouds, rain, etc. Why don't they use LASER instead to measure the density of the weather ahead?
RADAR has been known to return false signals of weather ahead (i.e. clear cloud, low density).
Would LASER be a more accurate application as LASER has been used in many other areas such as measuring terrain topography, density of some materials, temperature, etc.
P.S Please forgive my ignorance if this technology is already in use for this application.
