Welcome to the International Climate Network Working Group Website

</a>

The International Climate Network Working Group (ICNWG), formed under the Earth System Grid Federation (ESGF), helps set up and optimize network infrastructures for ESGF climate data sites located around the world. ESGF is a coordinated multi-agency, international collaboration of institutions that continually develop, deploy, and maintain software needed to facilitate and empower the study of climate change. Through ESGF, users access, analyze, and visualize data using a globally federated collection of networks, computers, and software.

The ICNWG is a collaborative effort between international network organizations in Australia (AARnet), Germany (DFN), the Netherlands (SURFnet), the UK (Janet), and the US (ESnet), as part of the Enlighten Your Research Global program. As ESGF paves the way for a new era in climate system analysis and understanding, ICNWG will put into place a new set of networking best practices to effectively transport hundreds of petabytes of future large-scale climate data. The world image above shows the five data centers looking to achieve consistent site-to-site data transfer rates ranging from 4 to 8 gigabits per second.
