What solar radiation received at earths surfAce?

The solar radiation received at Earth's surface, known as solar insolation, averages about 1,000 watts per square meter under clear skies at noon. This radiation varies based on factors such as geographic location, time of year, and atmospheric conditions. Approximately 30% of incoming solar radiation is reflected back into space, while the remaining energy is absorbed by the atmosphere and Earth's surface, driving weather patterns and supporting life.
