青藏高原地区500米分辨率的8天产品集（2000-2019）

1）数据内容：本数据集包含从2000-2019年青藏高原地区MODIS长时序光合有效辐射分数(FPAR)产品、地表总初级生产力产品（GPP）产品、Npp产品、蒸散发产品（ET）和叶面积指数（LAI）产品。2）数据来源及加工方法：FPAR产品和LAI产品来自第六版MODIS Terra MOD15A2H产品集，GPP和NPP产品均来自MODIS Terra MOD17A2H产品集，蒸散发产品来自MODIS Terra MOD16A2；通过USGS网站下载，利用GDAL插件进行拼接和转投影得到；3）数据质量描述：每种产品均有相应的质量文件，标识了云、雪、无效值等，以有效位编码方式存储。4）数据应用成果及前景：在森林、农业、生态等领域长时序信息挖掘分析方面具有重要的应用价值。

1) Data Content: This dataset contains MODIS long-time-series products of Fraction of Photosynthetically Active Radiation (FPAR), Gross Primary Productivity (GPP), Net Primary Productivity (NPP), Evapotranspiration (ET), and Leaf Area Index (LAI) over the Qinghai-Tibet Plateau from 2000 to 2019.
2) Data Source and Processing Method: The FPAR and LAI products are sourced from the Version 6 MODIS Terra MOD15A2H product collection, while GPP and NPP products are derived from the MODIS Terra MOD17A2H product collection, and the ET product comes from MODIS Terra MOD16A2. All products were downloaded from the USGS website, then mosaicked and reprojected using the GDAL plugin.
3) Data Quality Description: Each product has a corresponding quality file that identifies clouds, snow, invalid values and other anomalies, and is stored using bitwise encoding.
4) Data Application Achievements and Prospects: This dataset has important application value in the mining and analysis of long-time-series data in fields such as forestry, agriculture and ecology.
