NCDC NOMADS GrADS Data Server # 2

This GrADS Data Server (GDS) is provided by the NOAA Operational Model Archive and Distribution System (NOMADS) Project and is maintained by NOAA at the National Climatic Data Center . This server provides online access to scientific datasets.

NCDC NOMADS GrADS Data Server # 1

The catalog for this GDS contains primarily static and low frequency datasets which do not require frequent catalog reloads. This includes reanalysis, historic in-situ data, climate models, and numerical weather prediction models with less than four cycles per day.

The catalog on this GDS is reloaded every 6 hours to retrieve the latest data. Expect a few minutes of unresponsiveness during reloads.

Dataset Reload Times :
Typical reload takes 15-30 minutes
(Times are UTC Standard Time)
02:15 08:15 14:15 20:15
  • Dataset metadata directory

    Access Data, browse lists of files on this server. From these lists, you can select files and view metadata (e.g., grid description, dates, and variables) for those files.

    The metadata for each dataset also contains the URL for that dataset. With an OPenDap enabled client (e.g., GrADS), you can use this URL to access the dataset directly. Follow the "info" link for a dataset, copy the URL, and provide it to your client as required.

    For each model, the list of variables, timesteps, and levels provided by the "info" link is a composite for that model from runs over multiple grids and cycles. Each variable, timestep, and level in the list will not appear in all datasets for that model. To determine what variables, timesteps, and levels a specific dataset actually contains, view the "table of contents" for that dataset via the link below.
