Compaction of snow reduces the penetration of long and short wave radiation by reflecting more radiation off the snow.
2.
Heat and infrared radiation ( IR ) are produced when short wave radiation light hits the absorber plate, which is then trapped inside the collector.
3.
Solar thermal heat is trapped using the greenhouse effect; the greenhouse effect in this case is the ability of a reflective surface to transmit short wave radiation and reflect long wave radiation.
4.
A 4-component net radiometer serves to measure 4 separate components of surface radiation balance : SW in direct incoming short wave radiation, SW out or reflected short wave radiation, LW in diffused long-wave radiation from the sky and LW out long-wave radiation emitted by the ground surface.
