China has substantial data

but less information and insufficient knowledge

which results in poor international influence in global change research;thus

changing this situation is urgent.In 2016

a new project of the National Key Research and Development Program on Global Changes and Adaptation entitled

"Big data on global changes:Data sharing platform and recognition"

is launched.The project attempts to establish a global change-big data（GloBiD） sharing platform to change the current situation.This paper introduces this project

which comprises the establishment of three fast processing systems of global data（i.e.

multi-source data aggregation and processing system

fast production system on global satellite products with 30 m spatial resolution

and fast production system on FY satellite products）

uncertainty analysis of multi-source data impact on global changes

and the recognition of sensitive factors of global change driven by big data.Cloud technology

cluster computing

Apache Spark engine

Apache HBase

and HDFS data storage technology are adopted to build the GloBiD sharing platform.This project will provide high-quality data for the global change research of China.It will also provide valuable information on the main problems of global change for policy making based on the recognition of sensitive factors.Hopefully

the establishment of scientific recognition and data sharing platform of global change data will promote the development of the global change research of China in the future.
