摘要
本文根据地面反射率变化的原因,将其分解为自身变化、随机变化和随太阳高度角变化三种形式。对青藏高原上改则等4站地面反射率的自身变化和随太阳高度角变化的初步分析,得到了一个较为满意的地面反射率与太阳高度角的函数关系,以及地面反射率自身变化的一些有用的规律。
Based on the physical cases of the surface albedo variation it could be divided into 3 types, i.e. self-, random variations and the variation with the sun's altitude. By the analysis of the observational data from 4 stations over the Qinghai-Xizang Plateau, a formula for representing the relationship between the surface albedo and sun's altitude, and some useful results about the self-variation have been obtained.
