The Mongolian Plateau, as the largest arid and semiarid Plateau in Northern hemisphere, plays an important role in the climate changes and sustainable development of the ecological environment. This date set provides spatio-temporal consecutively vegetation monitoring data, which uses the sinusoidal projection method and 16 days' synthetic data. The spatial resolution of this date set is 250m. This data set improves the low saturation point of NDVI observation, which is calculated on the basis of BRDF data. It is aslo carried out a variety of mask processing (water, cloud, aerosol, cloud and shadow). The date set contributes to long-term dynamic assimilation and vegetation data analysis, and also can be used to detecte vegetation status, biological chemistry, water cycle, global and regional climate research.
