1. The NOAA Operational Model Archive and Distribution System NOMADS CEOS-Grid Application Status Report Glenn K. Rutledge NOAA NCDC CEOS WGISS-19 Cordoba, Argentina March 7, 2005

2. The NOMADS Project partners realized the need to extend its distributed data access methods into the existing grid technology efforts. Even with the temporal and spatial sub-setting capabilities with NOMADS, larger channels could benefit the climate and weather research communities. NOAA NESDIS is to explore these new technologies and provide a learning curve to reap potential rewards in the long- term. Overview

3. foster research within the geo-science communities (ocean, weather, and climate) to study multiple earth systems using collections of distributed data, promote model evaluation and product development, develop institutional partnerships via distributed open technologies. provide distributed access to models and associated data, NOMADS Goals The NOAA Operational Model Archive and Distribution System

4. CEOS-Gird and NOMADS Earth System Grid (ESG) co-PI Dean Williams also a co-PI on NOMADS. Suggested involvement of NOMADS and CEOS-Grid. Pilot for high volume access thru both ESG and CEOS-Grid. Advance understanding of grid technologies within NOAA. CEOS-Grid server established at NCDC- Globus v4

9. GO-ESSP The Global Organization for Earth System Science Portal (GO-ESSP) is a collaboration initiated by NOMADS to build the infrastructure needed to create web portals to provide access to observed and simulated data within the climate and weather communities. The infrastructure created within GO-ESSP will provide a flexible framework that will allow interoperability between front-end and back- end software components. GO-ESSP is an international collaboration involving software developers from both Europe and the United States. Advancing Collaborations
