Shortwave radiation (SW) is radiant energy with wavelengths in the visible (VIS), near-ultraviolet (UV), and near-infrared (NIR) spectra. There is no standard cut-off for the near-infrared range; therefore, the shortwave radiation range is also variously defined. It may be broadly defined to include all radiation with a wavelength of 0.1μm and 5.0μm or narrowly defined so as to include only radiation between 0.2μm and 3.0μm. WebNov 9, 2024 · The aerosol characteristics are assumed to be the same, and the sky is assumed to be clear over the domain during the simulation. The direct SW radiation is calculated based on the differences in upwelling SW radiation in BASE and aerosol-radiation (AR-DE), aerosol-cloud (AC-SDE), and radiation-cloud (ARC-IDE) interaction …
