MODIS/Terra Surface Reflectance Daily L3 Global 0.05Deg CMG NRT

The MODIS/Terra Surface Reflectance Daily L3 Global 0.05Deg CMG Near Real Time (NRT) product provide an estimate of the surface spectral reflectance as it would be measured at ground level in the absence of atmospheric scattering or absorption. Low-level data are corrected for atmospheric gases and aerosols, yielding a level-2 basis for several higher-order gridded level-2 (L2G) and level-3 products. The short name for this product is MOD09CMG which provides Bands 1 through 7 in a daily level-3 product gridded on a simple 0.05 degree (5600-meter) Geographic projection. Data for each pixel is selected on the basis of low solar zenith angle, minimum Band 3 (blue) reflectance, and absence of cloud from level-3 intermediate files. Science Data Sets provided for this product include reflectance values for Bands 1???7, brightness temperatures for Bands 20, 21, 31, and 32, solar and view zenith angles, relative azimuth angle, ozone, granule time, and quality assessment.

MODIS/Terra表面反射率每日L3全球0.05度CMG近实时（NRT）产品提供了在无大气散射或吸收的情况下，地面水平测量表面光谱反射率的估计值。低层数据经过大气气体和气溶胶的校正，为多个高级别网格化L2G和L3产品提供了基础级数据。该产品的简称是MOD09CMG，它在一个简单的0.05度（5600米）地理投影上，以每日L3产品形式提供第1至第7波段。每个像素的数据基于低太阳天顶角、最小第3波段（蓝色）反射率和第3级中间文件中无云的条件进行选择。为该产品提供的科学数据集包括第1至第7波段的反射率值、第20、21、31和32波段的亮度温度、太阳和视天顶角、相对方位角、臭氧、数据块时间和质量评估。
