shortwave radiation

[′shȯrt′wāv ‚rād·ē′ā·shən]
(electromagnetism)
A term used loosely to distinguish radiation in the visible and near-visible portions of the electromagnetic spectrum (roughly 0.4 to 1.0 micrometer in wavelength) from long-wave radiation (infrared radiation).

When a measurement point adjacent to a faccade becomes exposed to direct solar radiation, the radiation load increases significantly due to the additional lateral components, in some extent due to the reflected shortwave radiation (from the building wall), but in a great extent due to the emitted longwave radiation of the heated facade.

Leaves at the top of a canopy receive more shortwave radiation than leaves inside the canopy because radiation decreases with canopy depth.
The ocean absorbs shortwave radiation and re-emits longwave radiation (infrared rays).
It calculates incoming shortwave radiation each day at 12 min intervals from sunrise to sunset and incoming and outgoing longwave radiation from air and land surface temperatures.
Micrometeorological measurements at the site included 2 m air temperature and relative humidity (Vaisala HMP45C), solar irradiance and reflected shortwave radiation (300-2800 nm), and incoming and emitted longwave radiation (4500-42 000 nm) (Kipp and Zonen CNR4 net radiometer, including an integrated ventilation unit).

This means that shortwave radiation generally from solar sources is omitted, which affects the accuracy of the apparatus in determining MRT.
Tinted glass, or tinted coatings, can prevent even more heat transmission by blocking the shortwave radiation of heat, together with visible light.
These greenhouse gases cloak Earth like a blanket and allow shortwave radiation from the sun to pass through the atmosphere and warm the planet.
Using this model incoming solar shortwave radiation at earth's surface has been estimated at two stations for two months.
