ARCO-OCEAN

ARCO-OCEAN is an analysis-ready cloud-optimized dataset providing physical properties of the ocean, waves, and sea ice for a period of about 28 years between the 1st of January 1993 and the 30th of June 2021. The dataset includes also atmospheric and hydrological variables that would be needed as boundary conditions and used to drive a numerical simulation. The dataset is the result of collecting, processing, merging and optimizing for the cloud different data sources, all retrospective analyses

Useful for

Use cases llm-inferred: Ocean and wave boundary conditions for coastal or estuarine numerical modelling · Atmospheric and hydrological forcing inputs for marine-outfall or coastal flood studies · Training data for machine-learning prediction of sea state or water levels
Audience llm-inferred: coastal engineers · hydrologists · GIS analysts · data scientists

Limitations

Constraints llm-inferred: Retrospective reanalysis and hindcast data, not live observations · Record ends 30 June 2021, so it does not cover recent years · Update frequency is variable, so refresh timing is not guaranteed
