Abstract:

Vegetation index data products are widely used in the inversion of physical and chemical parameters of vegetation, land cover classification and changes studies. Traditional vegetation index products, such as AVHRR-NDVI, are sensitive to soil background changes and have the problem of high value saturation, which is easy to cause the decrease of sensitivity to vegetation detection. The China’s Terrestrial UNVI Multidimensional Dataset (2018-2021) was developed based on the MODIS surface reflectance product MOD09GA, using the Universal Pattern Decomposition algorithm UPDM (Universal Pattern Decomposition Method), which takes 16 days as the synthesis cycle. The practices show that the UNVI has more advantages in reflecting the change of vegetation cover and quantitative inversion of vegetation physical and chemical parameters compared with traditional NDVI products. The synthesis algorithm takes the number of days without cloud data in the synthesis period N as the judgment condition, and uses the Angle normalized synthesis method, the maximum synthesis method in a limited perspective, the direct calculation method and the maximum synthesis method MVC as the main synthesis algorithm to calculate the UNVI. Thus, the 2018-2021 China terrestrial UNVI products with a time resolution of 16 d and a spatial resolution of about 463 m was synthesized. The dataset includes the UNVI products of China terrestrial vegetation indices in 23 time periods with 16 d intervals from 2018 to 2021. The UNVI dataset is archived in .mdd format, and consists of 8 data files with data size of 43.5 GB (Compressed to 4 files with 12.5 GB). The tool and program for .mdd data format can be accessed by the references [23] and [24].Browse
