Solar Radiation Hourly Averages

Solar radiation is the total electromagnetic radiation emitted by the sun which is received at our monitoring site. These values are expressed in Langleys per minute. A Langley is a unit of energy per unit area (1 gram-calorie/cm²) commonly employed in radiation measurements.
