Vegetation cover dataset of Mongolia from 1990 to 2022
Listed in ScienceDB
The study was conducted by the NASA Goddard Space Flight Center (GSFC) and NASA's Arctic-Boreal Vulnerability Experiment.
Description
A Normalized Difference Vegetation Index (NDVI) dataset provided by a research team supported by the ABoVE program. The data set is version 3g.v1 in ncf data format.
PyCharm was used to extract, crop and define projection data to obtain NDVI data with a spatial range of (41° -53 °N, 87-121 °E), a period of 15d and a resolution of 1/12°. The average value method was used to calculate the monthly value data for the data of 15d. The annual Value data is calculated by Maximum value Compo-sition (MVC).Using the calculated annual maximum fitting data of NDVI, the value that is closest to the cumulative percentage of NDVI "5%" is selected as NDVIsoil and the value that is closest to the cumulative percentage of NDVI "95%" is selected as NDVIveg.
