Implementing iRODS for Data Federation


The Atmospheric Science Data Center (ASDC) at NASA Langley Research Center is responsible for ingest, archive, and distribution of NASA Earth Science data in the areas of radiation budget, clouds, aerosols, and tropospheric chemistry. Currently, the ASDC supports more than 44 projects and has over 1,700 archived data sets, which increase daily. Managing such a vast amout of data presents a challenge to providing higher quality, more cost effective and efficient services, and greater access to our current science community users and future diverse customers.


In order to address this challenge, the ASDC is currently piloting the use of the iRODS Data System (Integrated Rule-Oriented Data System), which enables parallel, downloads of datasets from selected replica servers that can be located in different locations but still accessible by users worldwide. The ASDC’s implementation mission with iRODS is to establish a consolidated, shared services capability by leveraging the iRODS federation capability that will enable the ASDC to interface to the data holdings of other NASA centers such The NASA Center for Climate Simulation (NCCS) at Goddard Space Flight Center (GSFC).
