Solar radiation

Solar radiation refers to energy produced by the Sun, some of which reaches the Earth. This is the primary energy source for most processes in the atmosphere, hydrosphere, and biosphere. In the context of current global change, over the last 40 years scientists have measured slight fluctuations in the amount of energy released by the Sun and have found that global warming

Measurement of Solar Radiation

The solar radiance varies throughout the day from 0 kW/m 2 at night to a maximum of about 1 kW/m 2. The solar irradiance is strongly dependent on location and local weather and varies throughout each day. Solar irradiance measurements consist of global and/or direct radiation measurements taken periodically throughout the day.
