NOAA Open Data Dissemination (NODD)
NODD is NOAA's bulk-data dissemination program, providing free, low-latency public access to tens of terabytes per day of forecast model output, satellite imagery, radar, and observation archives through public-private partnerships with AWS, Google Cloud, and Microsoft Azure. Datasets include GFS, GEFS, HRRR, RAP, NAM, RRFS, GraphCast, GOES-16/17/18/19, NEXRAD Level II/III, and hundreds of climate archives — all addressable as S3/GCS/Azure Blob objects, without keys.
