Canopy height is the height (in meters) of the top aboveground vegetation.
Canopy height is an important structural variable as it directly influences a large number of processes. This variable is a major concern for agricultural, ecological and meteorological fields and their applications. For instance, canopy height has a direct impact on wind speed which is an important variable for weather forecasting and all the resulting applications.
Canopy height can be measured through field campaigns (see here) or remote sensed from LiDAR or radar sensors.
