The yearly remote sensing Rao’s Q index dataset of forests in China (2000-2017) was developed based on MOD09A1 data, integrated with the formula for Rao’s Q index. The temporal resolution of the data was one year, the spatial resolution was 5 km. The dataset is archived in .tif format, and consists of 72 data files with data size of 58.2 MB (Compressed into one file with 5.17 MB). The research paper based on this dataset was published in Acta Ecologica Sinica, Vol. 43, No. 8, 2023.
