Data Abstract
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.To extract EVIT via sinusoidal projection and 16 days' synthetic data.We should also take the atmospheric correction problems into account. The calculation of the date is based on BRDF correction and a variety of mask processing. Compared to the NDVI EVI time series, seasonal time series is more obvious, which can better reflect the seasonal variation characteristics of high vegetation covered area.
