On August 27, 2025, the NSF NCAR Climate Data Gateway (CDG) and Geoscience Data Exchange (GDEX) will be migrated into the RDA. Please update your bookmarks and citations.
The RDA Jira Help Desk will be unavailable starting August 25 at 5:00 PM MDT. Service will resume on August 26 under a new name: DATAHELP. All customer channels will automatically redirect to the new DATAHELP page.
Note: Since this dataset now has a duplicate copy in AWS, we will stop continuous updates of this dataset in the summer 2025.
The NCEP operational Global Data Assimilation System surface flux grids are on a T574 Gaussian global grid. Grids include analysis and forecast time steps at a 3 hourly interval from 0 to 9 hours. Model runs occur at 00, 06, 12, and 18 UTC daily. For real-time data access please use the NCEP data server.

Citation counts are compiled through information provided by publicly-accessible APIs according to the guidelines developed through the https://makedatacount.org/ 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.
