5. 2. Data Resources5Mirror DataAfter 4 years of efforts, International Scientific Data Service Platform has accumulated mass data resources . Including LANDSAT, MODIS, EO-1, DEM, NCARTime up to September , 2011, the volume of data reached 160 TB, the number of data entries reached 3,000,000Most of the data has provided online serviceData productsIn order to meet the needs of chinese user, besides the Mirrored initial Data, the platform processed a series of data productsNow there are 66 Mirrored initial Datasets and up to 40 Data products in the platform
6. 2. Data Resources--NCARNCAR: The National Center for Atmospheric Research (NCAR) is a federally funded research and development center devoted to service, research and education in the atmospheric and related sciences.Cooperation between CNIC & NCARCooperation between CNIC & NCAR started from 2008.The term of the renewed MOU is for a period of six years from 2011, up to 2017Contents: share data and user usage metrics In cooperation period, CNIC have about 14 datasets mirrored from NCAR for serving users in China, data quantity reach about 1TB.6
7. 2.Data Resources--LANDSATLANDSAT archive dataOn April 21, 2008, the USGS announced plans to provide all archived Landsat scenes at no charge to all users.On July, 2008,CNIC came to an agreement with USGS and began to mirror LANDSAT archive data.Data volume : 8TBAvailability: Online download form http://datamirror.csdb.cn/7

9. The Moderate-resolution Imaging Spectroradiometer (MODIS) offers a unique combination of features:It detects a wide spectral range: 36 bandsIt takes measurements at three spatial resolutions (250m,500m,1KM)I takes measurements all day, every dayIt has a wide field of view. These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.2.

15. 3. Multi-services -- Consultant OnlineConsultant OnlineSpecified staffs of platform and experts from different research fields provide consulting service for users.Question & Answer : User can raise question by Consulting Service System ,telephone or E-mail, Consultant will give serious reply as soon as possible.Data Reservation : From the Platform , user can reserve the data which they need but cannot download from website.Data Application & Express : the platform Provide Data application and data Express service. By this service, users can get mass of data by FTP Site. They can require us to post CD-ROM to them o if they need. Of cause they also can come to our laboratory and copy the data they need directly.15
