MODDISTerra星MOD09GQ250M地表反射率每日数据产品
收藏资源简介:
Modis表面反射率产品是表面波谱反射估计,低级数据产品进行了大气和气溶胶的校正,并在此基础上进一步处理产生了L2基础数据产品以及L2G(栅格化2 级产品)和L3数据产品。 MOD09GQ提供了1-2波段每日栅格化二级的数据产品(L2G),投影为正弦曲线投影,包括250米的反射率值和1公里的观测和地理位置统计值。此产品提供了1-2波段的反射率、质量评价、观测图层和观测数量信息。MOD09GQ可以和MOD09GA共同使用,因为MOD09GA存储了重要的质量评估和观测集合信息。
The MODIS surface reflectance products are estimates of surface spectral reflectance. Low-level data products have been corrected for atmospheric and aerosol effects, and further processed based on this to generate L2 basic data products, as well as L2G (gridded Level 2 product) and L3 data products. MOD09GQ provides daily gridded Level 2 products (L2G) for bands 1 and 2, which adopts a sinusoidal projection. It includes 250-meter reflectance values and 1-kilometer geolocation and observation statistics. This product provides reflectance data for bands 1 and 2, quality assessment information, observation layers, and observation count details. MOD09GQ can be used in conjunction with MOD09GA, as MOD09GA stores critical quality assessment and observation collection information.
