Abstract

The Netherlands Sciamachy Data Center, the data service center provided by SRON and KNMI, will be upgraded to offer additional functionality for end-users of Sciamachy data. One of the functionalities provided will be the possibility to select and process multiple Sciamachy files using different data processors, which can lead to intensive use of the limited computing and data storage resources available to NL-SCIA-DC, i.e. the NL-SCIA-DC will run out of resources. These limitations can be overcome by using GRID technology.

GRID technology provides secure ways of sharing resoures (e.g. data storage, computing power) between organizations over the Internet. Several large GRID environments have been successfully deployed, i.e. by the European EGEE project.

Our aim is to add user-requested functionality to NL-SCIA-DC for which currently the computer and/or storage resources are not available to the partners KNMI and SRON. GRID technology helps us to extent the functionality of NL-SCIA-DC without losing the current high-standard of security and to make efficient use of the resources available at KNMI, SRON and elsewhere.

The end result will be an integrated ‘griddified’ NL-SCIA-DC, integration of two organization domains (SRON and KNMI) using standard and open general purpose protocols and interfaces, delivering non-trivial quality of service to the Dutch and international atmospheric research community.
