COAWST model output for 10 typical, maximum and minimum representative years for Madeira and Porto Santo Islands waves studies. Variables included are significant wave height, wave direction, wave mean period, wave peak frequency and power density. This data represents the long-term, maximum and minimum climatology through a single year, constructed from a long-term period of 10 years measured data. Each climatology has twelve individual monthly simulations. The data has 1 km resolution, provided from COAWST. A coupled model with Weather Research and Forecasting (WRF), Regional Ocean Modelling System (ROMS) and WaveWatch III (WW3). Data in netcdf4 format.
