AB: To address a growing need for retrospective Global Climate Model (GCM) and NWP input and output data, the National Climatic Data Center (NCDC) along with the National Centers for Environmental Prediction (NCEP) and the Geophysical Fluid Dynamics Laboratory (GFDL) initiated the highly collaborative NOAA National Operational Model Archive and Distribution System (NOMADS). NOMADS (http:nomads.ncdc.noaa.gov) provides real-time and retrospective access to model and observational data by a wide variety of users using the Internet. The NOMADS system is one of the first operational systems of its kind and filled a gap in the geosciences community for retrospective model data access. Low bandwidth users will discover the NOMADS sub-setting capability for high volume datasets particularly useful. NOMADS provides model input and output data and products and other associated data and is an inter-operable network architecture with fully integrated data access and manipulation tools using a distributed, Web-services based format independent methodology. NOMADS allows temporal, spatial, and variable sub-setting to address the ever increasing spatial resolution of models and therefore volume and varied formats of data presented for archive and access at NCDC. This paper will describe the benefits of using NOMADS, and its most recent advances including a new Ensemble probabilities interface, the Live Access Server implementation across two NOAA Line Offices (NESDIS and NMFS); the model forecast aggregation capability being developed at Unidata and now installed on the NCDC NOMADS THREDDS Data Server; and other new services and products available on the NOMADS server at NCDC. Finally, this paper will describe the new operational National Weather Service (NWS) NOMADS capability currently being developed for deployment across the U.S.
