Full description

This database contains global daily wave observations from the Surface Wave Investigation and Monitoring (SWIM) wave scatterometer instrument onboard the China-France Oceanography Satellite (CFOSAT), aggregated into 1° by 1° geographical bins. Specifically, the dataset includes SWIM Level-2 standard wave parameters derived from the 10° incidence-angle beam, wave products calibrated against in-situ wave buoy observations, improved mean wave period estimates, and collocated wave hindcast model outputs. The data have been homogenised into a consistent and easily usable format. This is a trial dataset, and its calibration and validation is an area of current active research.

Lineage

Maintenance and Update Frequency: biannually
Statement: The CFOSAT-SWIM dataset contains available global wave observations aggregated into a 1° by 1° geographical bins. The collection includes standard wave parameters from SWIM measurements, selected wave parameters also calibrated against NDBC buoy observations, collocated wave hindcast model outputs, and improved mean wave period estimates. Relevant matchups and calibration details can be found in Canto et al., 2026, Ocean Dynamics.
