Nephoscope is a term used to refer to an instrument that is used to track and study clouds. It works by reflecting the image of the clouds onto a vertical surface, allowing meteorologists to observe the features of the clouds. However, there are other terms that can be used to describe the same instrument. For instance, it is also referred to as a cloud reflectometer, cloud mirror, or cloud classifier. In addition to these terms, there are other words that are synonymous with nephoscope, such as cloud watcher, cloud observer, or cloud spotter. Regardless of the terminology used, the function and purpose of the instrument remains the same.
