To promote academic researches on earth environment utilizing satellite data, research infrastructure such as satellite data reception, processing, distribution and archival systems should be fully provided. The means to enhance the infrastructure were discussed by a working group and "Satellite Data Center via Network" has been proposed. This concept has three principles; (1) To realize necessary functions by organizing experts distributed all over Japan and connecting them by network, (2) To realize "Satellite Data Center via Network" for GMS and NOAA Satellites, which are widely used for research, and (3) Satellite data set oriented to specific research area should be generated by researchers having definite research purposes in cooperation with researchers in the fields of sensor algorithms and hugh volume data processing. Utilization of the Science Information Network (SINET) has been discussed to realize this concept, and to accelerate this project an experiment "Network Utilization for Wide Area Use of Satellite Image Data" under "Cooperative Experiment on Multimedia Communication" has been introduced. And the roles of the Institute of Industrial Science, University of Tokyo to contribute this project has been described.
