To ensure the high fidelity of the simulations, the model has been validated rigorously historical observations obtained from buoys operated by the Caribbean Coastal Ocean Observing System. All buoy data from the San Juan, Rincon, Vieques and Ponce buoys during the CARICOOS era (2009 to present) has been used to quantify model performance, and the results are shown below. Model - data comparison against the St. John CARICOOS buoy will be completed as part of a second phase of the study sponsored by CARICOOS which will expand some components of the wave climate atlas to the US Virgin Islands.
