NCEP Global Ocean Data Assimilation System (GODAS)

| DOI: 10.5065/ZAHZ-3174

The National Centers for Environmental Prediction (NCEP) uses a Global Ocean Data Assimilation System (GODAS) to routinely produce monthly and pentad (5-day) mean global ocean gridded data. The analysis system, that was originally applied only to the tropical Pacific, has evolved to use GFDL MOM v3 model and give near global coverage. Briefly, the model domain specifications are 65N to 75S, 1 degree resolution with 1/3 degree resolution within 10 degree of the equator, 40 levels and 10 meter resolution in the upper 200 meters. These data are a valuable community asset for monitoring different aspects of ocean climate variability.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the project. If journals do not provide citation information to these publicly-accessible services, then this citation information will not be included in RDA citation counts. Additionally citations that include dataset DOIs are the only types included in these counts, so legacy citations without DOIs, references found in publication acknowledgements, or references to a related publication that describes a dataset will not be included in these counts.
