资源简介：
The MYD09GQ Version 6.1 product provides an estimate of the surface spectral reflectance of Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) 250 meter (m) bands 1 and 2, corrected for atmospheric conditions such as gasses, aerosols, and Rayleigh scattering. Along with the 250 m bands are the Quality Assurance (QA) layer and five observation layers. This product is intended to be used in conjunction with the quality and viewing geometry information of the 500 m product (MYD09GA). Known Issues
MYD09GQ 6.1版产品可反演Aqua卫星搭载的中分辨率成像光谱辐射计（Moderate Resolution Imaging Spectroradiometer，MODIS）250米（m）波段1与波段2的地表光谱反射率，该反射率已针对大气气体、气溶胶与瑞利散射等大气条件完成校正。除250米波段数据外，该产品还附带质量保障（Quality Assurance，QA）图层与5个观测图层。本产品需配合500米分辨率产品（MYD09GA）的质量信息与观测几何信息一同使用。已知问题
