Gross primary productivity (GPP) refers to the amount of organic carbon fixed by plants in the process of absorbing CO2 through photosynthesis in a unit of time. The MODIS gross primary productivity product data set in the upper reaches of the Yangtze River, China, is based on the cutting and splicing of MOD17A2H (version 006) products. The data product provides the estimated GPP value, which can be used as the input of the data model to calculate the terrestrial energy, carbon, water cycle process, and vegetation biogeochemistry. The time range is from February 18, 2000 to August 30, 2022. The spatial resolution is 500m, the time resolution is 8-day cumulative comprehensive value, and the data coordinate system is the WGS84 geographic coordinate system.
File name: GPP data is stored in GeoTiff format. The file name is "MOD17A2H.006_Gpp_500m_dayYYYYDDD_aid0001. tif", where YYYY represents the year and DDD represents the date. For example, "MOD17A2H.006_Gpp_500m_doy2000057_aid0001.tif" means that the file describes the GPP range on the 57th day of 2000.
Data reading method: All GeoTiff files in the dataset can be directly opened using Arcmap or ENVI.
