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 their operational 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). CFSv2 monthly atmospheric, oceanic and land surface output products are available at 0.3, 0.5, 1.0, 1.9, and 2.5 degree horizontal resolutions as 6-hourly diurnal monthly means (0000, 0600, 1200, and 1800 UTC) and regular full monthly means. For more information about CFS, please see http://cfs.ncep.noaa.gov/ [http://cfs.ncep.noaa.gov/].

The National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) was initially completed over the 31-year period from 1979 to 2009 and has been extended to March 2011. CFSR was initialized 4 times per day (0000, 0600, 1200, and 1800 UTC), and the 6-hourly atmospheric, oceanic and land surface analyzed products are available at 0.3, 0.5, 1.0, 1.9, and 2.5 degree horizontal resolutions, along with forecast hours 1 through 6. However, not all parameters are available at all resolutions and some parameters are not analyzed (e.g. 2 meter temperature, 10 meter winds), so please consult the detailed metadata for exact descriptions of what is available.

The National Centers for Environmental Prediction (NCEP) Climate Forecast System Reanalysis (CFSR) was initially completed over the 31-year period from 1979 to 2009 and has been extended to March 2011. NCEP has created selected time series products at hourly temporal resolution by combining either 1) the analysis and one- through five-hour forecasts, or 2) the one- through six-hour forecasts, for each initialization time. Please note that NCEP only created time series for parameter/level combinations that they thought would be most useful to users. Time series that do not exist in this dataset can be created from the full 6-hourly products dataset at https://rda.ucar.edu/datasets/ds093.0/ [https://rda.ucar.edu/datasets/ds093.0/]. For more information about CFSR in general, please see this page [https://cfs.ncep.noaa.gov/cfsr/]. For data to extend CFSR beyond March 2011, please see the Climate Forecast System Version 2 (CFSv2) datasets.

As a value-add for longer-term climate research, the CISL RDA has created time series of individual parameter-levels from the regular monthly means. Please note that not all parameters are available at all levels and that some parameters are not analyzed (e.g. 2 meter temperature, 10 meter winds), so please consult the detailed metadata for exact descriptions of what is available.For more information about CFSR in general, please see NCEP's page [https://cfs.ncep.noaa.gov/cfsv1.html]. For data to extend CFSR beyond December 2010, please see the Climate Forecast System Version 2 (CFSv2) datasets.
