Definition

Surface incident longwave radiation is a measure of the incident longwave radiant energy from the atmosphere to the Earth’s surface. It is an important measured quantity in analyzing of the energy balance in the Earth system. Surface incident longwave radiation can be expressed by radiant energy flux per unit of area.

Applications

  1. Environmental issues
  2. Water cycle
  3. Energy cycle
  4. Weather forecast
  5. Climate prediction modeling
