It is an instrument used to collect and measure the amount of rain that falls. However, these devices are painless, efficient, and extremely accurate in diagnosing the eye’s health status. There are instruments called Ceilometers which can measure cloud height and cover, but they're not especially accurate for cover (they are quite good for cloud height, especially at night) as a cloud can sit over the instrument and give a false reading. Simard and colleagues used lidar data from the Geoscience Laser Altimeter System , the primary instrument aboard NASA’s Ice, Cloud and land Elevation Satellite (ICESat-1) satellite (in orbit from 2003 to 2009), to get measurements of maximum canopy heights for mangroves. Cloud cover (also known as cloudiness, cloudage, or cloud amount) refers to the fraction of the sky obscured by clouds when observed from a particular location.
