Earth system scientific data sharing mode based on Adaptable Global Spatial Grid

An efficient data sharing system is vital to Earth System Science (ESS) researches. However, current systems mainly focus on standards, policies and software environments. None of them pay much attention to spatial references. Adaptable Global Spatial Grid (AGSG), was selected as a unified spatial reference for data sharing. Methods of data representation based on AGSG was introduced and the mode of data sharing based on AGSG was presented. Merits of easy reusing of ESS data, uniform requests, and transparent accessing of multi-sources data were shown in the mode. Potential extensions to the volunteer services of data sharing and cloud technology were discussed.
