The MODOCGA V6 ocean reflectance product consists of 1 kilometer reflectance data from Terra MODIS bands 8-16. The product is referred to as ocean reflectance, because bands 8-16 are used primarily to produce ocean products, but this is not an ocean product as the tiles produced are land tiles.

MODOCGA V6海洋反射率产品由Terra MODIS 8-16波段的1公里反射率数据组成。该产品被称为海洋反射率，因为8-16波段主要用于生产海洋产品，但这并不是一个海洋产品，因为生产的瓦片是陆地瓦片。
