With the support of the CAS’s space-time Third Pole environment project, which is a leading part of the Earth Big Data Science Project.To establish an open Third Pole scientific data center and intergrate the present data,updated data and new product,then provide overall Third Pole information service.Through a collection of the Third Pole cryosphere modeling, the water cycle modeling,the ecosystem modeling,multi-sphere modeling and socioeconomic assessment modeling, then standardize and unify the input and output interface and build the Third Pole scientific model libraries.By means of interoperation and sharing of “big data and cloud service” and “digital earth scientific platform”,a comprehensive platform of Third Pole database,modeling libraries and method libraries will achieve and provide Third Pole big data and information for the earth big data scientific platform.
