Google Earth Engine ——MCD43A3 V6反照率模型数据集是一个每天16天的产品。它提供了MODIS表面反射波段（波段1到波段7）以及3个宽光谱波段（可见光、近红外和短波）

The MCD43A3 V6 Albedo Model dataset is a daily 16-day product. It provides both directional hemispherical reflectance (black sky albedo) and bihemispherical reflectance (white sky albedo) for each of the MODIS surface reflectance bands (band 1 through band 7) as well as 3 broad spectrum bands (visible, near infrared, and shortwave). Each 500m/pixel daily image is generated using 16 days of data, centered on the given day. A quality band is also provided for each of the 10 albedo bands.

MCD43A3 V6反照率模型数据集是一个每天16天的产品。它提供了MODIS表面反射波段（波段1到波段7）以及3个宽光谱波段（可见光、近红外和短波）的定向半球反射率（黑天反照率）和双半球反射率（白天反照率）。每张500米/像素的日图像是用16天的数据生成的，以给定日期为中心。还为10个反照率波段中的每一个提供了一个质量波段。
