Abstract:In this paper,using MODIS albedo retrieval quality data MCD43A2,the spatial and temporal distribution characteristics of surface albedo retrieval quality over China during the period of 2003-2015 are statistically analyzed.The results are as follows:(1)There was a clear difference in the spatial distribution of MODIS surface albedo retrieval quality in China.The albedo retrievals with the best quality of full inversion(flagged as 0)were mainly distributed in northern,northeastern,northwestern,and the Midwestern region of southwestern China.The albedo retrievals with the magnitude inversion(flagged as 3) were mainly distributed in eastern,central,southern,and the mid eastern region of southwestern China.The fill value(flagged as 15) was mainly distributed in some regions of central,southern,eastern and southwestern China.(2)In spring,summer and fall,the areas of only northeastern,northern and northwestern China had more than 60% which could be obtained with high accuracy MODIS surface albedo,so as to meet the climate and land-surface model accuracy requirements.In addition,only 40%-60% of the area of southwestern China and less than 20% of that of eastern,central and southern China could be obtained with high accuracy MODIS surface albedo to meet the climate and land-surface model accuracy requirements throughout the year.(3)The percentage of the magnitude inversion is low,being generally less than 50%,all throughout China.Meanwhile,that in eastern and central China is more than 40% in summer and autumn.In central and eastern China in summer and winter,as well as in southern China in spring,summer and winter,the percentage of the fill value is relatively high(above 50%),especially in southern and central China,where the figure reaches up to 80%.
