Abstract
YBJ-ARGO cosmic ray telescope is a Chinese-Italian collaboration located at Yangbajing, Tibet, at high altitude of 4300 meter above sea level. It consists of a single layer of RPC's (Resistive Plate Counters) covering an area of approximately 6500 sqm and the physics aim is to study cosmic rays, mainly cosmic gamma-radiation, at an energy threshold of ~100 GeV. The cosmic ray experiment will generate 200 TB raw data every year that have to be processed and analyzed in Beijing and Italy. To facilitate the data procession and distribution, a data grid infrastructure is being built. This report shows the scheme to transfer data from Tibet to Beijing and Rome and process the data by the grid-based computing resources at the two sites. A web portal system has been built to make the available to physicists worldwide.
