NOAA Coastal Ocean Reanalysis (CORA)
RPS worked with the CORA group to optimize this very large dataset for cloud-based access.
Atlantic reanalysis
- HSOFS mesh (~1.8 million nodes)
- 40 years of hourly data every 500m along the coast, including within bays, estuaries, and coastal river mouth entrances
- ~70 TB of storage
Pacific reanalysis
- GSTOFS mesh (~450k-2.2m nodes)
- Resolution down to 80m for Hawaii and US West Coast
- 90-120m for Pacific Islands
- ~300 TB of storage
Applying Kerchunk
After applying kerchunk to cloud-optimize the data, we were able to perform the following analysis:
| Function | Optimized | Original |
|---|---|---|
| Month long time-series | 2 s | ?? |
| Get 141 annual time series | 3 min | 30 min |
| Daily max water level | 6 s | >90 min |
