摘要: 根据1997年10月至1998年11月青藏高原西部改则和狮泉河两个自动气象站连续观测的大气、辐射和土壤资料,在分析高原西部地面反射率冬、夏季日变化特征的基础上,重点研究了地面反射率与土壤和大气若干重要因子(如土壤湿度、土壤温度、空气相对湿度、空气温度)的关系。研究结果有助于改进气候模式和卫星遥感中高原地面反射率的参数化方案。

Abstract: By using the continuous observational data of air,radiation and soil from two sites of automatic weather station(AWS) at Gaize and Shiquanhe on the western Qinghai-Tibet Plateau in the period from October 1997 to November 1998,the diurnal variations of surface albedo in summer and winter are analyzed.Furthermore,the stress of this paper is put on discussing the relationship between surface albedo and some meteorological factors(such as soil moisture,surface moisture temperature,air relative humidity and air temperature).The results are helpful to improve the parameterization schemes of surface albedo in climate model and satellite remote sensing.
