Data coverage
This repository contains references to datasets published to the NOAA Open Data Dissemination Program. These reference datasets serve as index files to the original data by mapping to the Zarr V2 specification. When multidimensional model output is read through zarr, data can be lazily loaded (i.e. retrieving only the data chunks needed for processing) and data reads can be scaled horizontally to optimize object storage read performance. The process used to optimize the data is called kerchunk. RPS runs the workflow in their AWS cloud environment every time a new data notification is received from a relevant source data bucket. These are the current datasets being cloud-optimized. Refer to those pages for file naming conventions and other information regarding the specific model implementations: NOAA Operational Forecast System (OFS) NOAA Global Real-Time Ocean Forecast System (Global RTOFS) NOAA National Water Model Short-Range Forecast Filenames follow the source dataset’s conventions. For example, if the source file is nos.dbofs.fields.f024.20240527.t00z.nc Then the cloud-optimized filename is the same, with “.zarr” appended nos.dbofs.fields.f024.20240527.t00z.nc.zarr Data Aggregations We also produce virtual aggregations to group an entire forecast model run, and the “best” available forecast. Best Forecast (continuously updated) - nos.dbofs.fields.best.nc.zarr Full Model Run - nos.dbofs.fields.forecast.[YYYYMMDD].t[CC]z.nc.zarr - CC is the model run cycles, 00, 06, 12, 18 , or 03, 09, 15, 21 for nowcast and forecast runs - YYYY = year, MM = month, DD = day Cloud optimization workflows supported by RPS Group, a Tetra Tech Company
Access & permitted use
Review the publisher’s documentation for availability, eligibility and permitted uses, including commercial analysis, model training and redistribution.
NOAA data disseminated through NODD are open to the public and can be used as desired. NOAA makes data openly available to ensure maximum use of our data, and to spur and encourage exploration and innovation throughout the industry. NOAA requests attribution for the use or dissemination of unaltered NOAA data. However, it is not permissible to state or imply endorsement by or affiliation with NOAA. If you modify NOAA data, you may not state or imply that it is original, unaltered NOAA data.
