MOD17A3HGF NPP dataset

<b>Using the GEE cloud platform, MOD17A3HGF NPP data was retrieved based on the image set ID “MODIS/006/MOD17A3HGF”. The maximum value composite method was employed to generate the NPP image dataset covering the period 2000-2020. The ee.ImageCollection.toBands() function was then applied to convert the image collection into individual multispectral images containing each image within the collection. This format facilitates NPP trend analysis and Mann-Kendall trend testing within the R environment.</b>Land use dataset:<i>https://www.ngcc.cn/</i><i>Climate dataset：</i>https://climexp.knmi.nl/<i>Historical wildfire dataset：</i>https://firms.modaps.eosdis.nasa.gov/Surface reflectance dataset：https://developers.google.com/earth-engine/datasets<br>
