NCEP Climate Forecast System Version 2 (CFSv2) Selected Hourly Time-Series Products

| DOI: 10.5065/D6N877VB

The National Centers for Environmental Prediction (NCEP) Climate Forecast System (CFS) is initialized four times per day (0000, 0600, 1200, and 1800 UTC). NCEP upgraded CFS to version 2 on March 30, 2011. This is the same model that was used to create the NCEP Climate Forecast System Reanalysis (CFSR).

Selected CFS time series products are those that are expected to be most useful to users of the dataset, but the products here are by no means an exhaustive compilation of all of the possible products that could be created from the full 6-hourly CFS dataset.

The products here are available at 0.2, 0.5, 1.0, and 2.5 degree horizontal resolutions at hourly intervals by combining either 1) the analysis and one- through five-hour forecasts, or 2) the one- through six-hour forecasts, for each initialization time. Beginning with January 1, 2011, these data are archived as an extension of CFSR.

The files in this dataset are grouped by month, so data for a particular month are not available until a few days into the subsequent month. If you need data for the current month, please consult the CFSv2 dataset that contains the complete suite of 6-hourly products.

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.
