This dataset includes 4 main files obtained from WAVEWATCH III run using a model set up described in Alday and Ardhuin (2023) as "T707-GQM", and many ancillary files describing details of the model set up and basic reading and analysis tools that combine model and buoy data. This model is unique in including quasi-exact 4-wave interactions and coastal and iceberg wave reflection, but uses a relatively coarse spectral resolution (24 directions and 36 frequencies).  Tools for analysis of these model output in combination with in situ buoy data (https://doi.org/10.17882/99739) are available here: https://github.com/ardhuin/swellSWOT.
