GLASS产品-年均植被总初级生产力GPP_avhrr(0.05°)（1982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°)（1982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 relevant files of the annual vegetation gross primary productivity dataset GPP_avhrr (0.05°, 1982) under the Global Land Surface Characteristic Parameters Product include HDF and XML files. Data entities are stored in the HDF file, while product metadata is stored in both HDF and XML files.

The GLASS Product features long-term time series, high spatial resolution and high accuracy, providing reliable foundational support for global environmental change research. It can be widely applied to dynamic monitoring of atmosphere, vegetation cover, water bodies and other aspects at global, continental and regional scales. When combined with climate change characterization parameters such as air temperature and precipitation, it is utilized for global change analysis.

This dataset can provide excellent scientific basis, technical and data support for studying the evolutionary laws of global ecological environment, ecological environment monitoring, resource development and socio-economic sustainable development.
