The NOAA Operational Model Archive and Distribution System - (NOMADS), provides distributed, web-service access for real-time and retrospective, format-independent climate and weather model data and related datasets.
NOAA NCDDC, with partners including National Weather Service National Centers for Environmental Prediction (NCEP) and the Northern Gulf Institute, has created this NOMADS node for ocean-model access, called OceanNOMADS. This site provides retrospective access to long timeseries of output from mature ocean modeling and prediction systems, including models from NOAA's National Weather Service (NWS) and the U.S. Navy. Long-term archival of selected model fields is done at NOAA's National Oceanographic Data Center. A developmental version of the OceanNOMADS capability developed under the NGI Ecosystem Data Assembly Center (EDAC) project continues to offer data access and analysis-tool development as well as access to newer NOAA and Navy ocean prediction capabilities, with a geographic focus on the Gulf of Mexico.
Note: Users who require real-time access to NOAA and Navy model fields are directed to the high-availability servers at NCEP.

This site offers a variety of web-based data services including bulk file download, OPeNDAP subsetting, timeseries aggregation through Thredds Data Server, and visualization through ERDDAP. Due to structural differences between different datasets, not all services are available for all models. Choose a model dataset at right to access available data and services.
