Question

Insolation is the measure of solar radiation energy at a location during a given time (incoming solar radiation). When did the radiometer measure the most insolation? How do you know?

Answer 1

The radiometer measured the most insolation when the sun's rays were directly overhead at the location, which occurs at solar noon. The knowledge of when the radiometer measured the most insolation comes from understanding the concept of the sun's movement across the sky and its angle of elevation at different times and locations.

Step-by-step explanation:

The radiometer measured the most insolation during the time when the sun's rays were directly overhead at the location. This occurs at solar noon, which is when the sun is at its highest point in the sky. At this time, the insolation is maximum because the sunlight has to travel the shortest distance through the atmosphere, resulting in less scattering and absorption. For example, if the location is at the equator, the sun is directly overhead at solar noon every day. However, if the location is at a higher latitude, the sun may only be directly overhead at certain times of the year. The knowledge of when the radiometer measured the most insolation comes from understanding the concept of the sun's movement across the sky and its angle of elevation at different times and locations.
