SFC
Description
The surface reflectivity is the relative ratio of the amount of light reflected by the surface and the sunlight reaching the surface. It has no unit and generally has a value between 0 and 1. Surface reflectivity is affected by the surface states(composition, shape), atmospheric transmittance, and the position of the satellite and the sun.
Applications
The surface reflectance of the ultraviolet/visible domain can be used as a major input and analysis data in research fields such as ecosystem, environment, and climate change in East Asia including the Korean Peninsula. It can be used as fundamental data to compare the state and changes of the surface environment through the estimation of the surface reflectance in the ultraviolet/visible domain and the spatiotemporal distribution characteristics.
If the surface reflectance is greater than 1 or less than 0, the effect of clouds, ozone, or nitrogen dioxide is significant, the result should be used with caution.
