IS-ENES [ees-enes]InfraStructure for the European Network for Earth System

Modelling

IS-ENES will develop a virtual Earth System Modelling Resource Centre (vERC)

Martin Juckes, BADC

• Funded by EU Framework Programme 7 to develop infrastructure for Earth System Modelling, 7.6M€, 4 years.

• 20 partners, led by IPSL.• Objectives include:

education, enhancing model efficiency, model evaluation tools, data management and services for data users.

IS-ENES:key facts

IS-ENES: data management

• Core funding objective: enhance European capability to deal with large and diverse datasets from Earth System Modelling projects, using distributed data archives.

• Software to support EU contribution to CMIP5/AR5 archive

A few aims

• A comprehensive data policy • Optimise resource usage in execution of user

services • Enhance the efficiency of metadata transfer

between nodes • OGC, wget and OPeNDAP • Visualisation • Regional model support (OPeNDAP + OASIS)• Slice, regrid, differences and aggregates• Checksums• Post download support {e.g. fileStatusAtProvider:
