GLASS产品-年均植被总初级生产力GPP_avhrr(0.05°)（2008年）

全球陆表特征参量产品-年均植被总初级生产力GPP_avhrr(0.05°)（2008年）产品相关文件包括HDF和XML两个文件，其中数据实体存储在HDF文件中，产品的元数据信息存储在HDF和XML文件中。GLASS产品具有长时间序列、高分辨率、高精度的特征，为研究全球环境变化提供了可靠的依据，能够广泛应用于全球、洲际和区域的大气、植被覆盖、水体等方面的动态监测，并与气温、降水等气候变化表征参数结合起来，应用于全球变化分析。可为全球生态环境演变规律、生态环境监测、资源开发和社会经济可持续发展提供很好的科学依据、技术和数据支持。

The Global Land Surface Characteristic Parameters Product - Annual Mean Vegetation Gross Primary Productivity GPP_avhrr (0.05°) (2008 version) includes two types of relevant files: HDF and XML files. The data entities are stored in the HDF file, while the product metadata is stored in both HDF and XML files. The GLASS product features long-time series, high spatial resolution and high accuracy, providing reliable foundations for global environmental change research. It can be widely applied to dynamic monitoring of the atmosphere, vegetation cover, water bodies and other aspects at global, continental and regional scales, and can be combined with climate change characterization parameters such as air temperature and precipitation for global change analysis. Furthermore, it can provide excellent scientific basis, technical and data support for studying the evolutionary laws of global ecological environment, ecological environment monitoring, resource development and socioeconomic sustainable development.
