Arctic regional maximum wave heights and trends derived from CMIP5-based ocean wave simulations for the periods 1979-2005 and 2081-2100

This dataset contains relative trends of annual and monthly regional maximum ocean wave heights in the Arctic, and data for three predictors derived from surface winds and sea ice concentration. It also contains estimates of historical (1979-2205) and future (2081-2100, RCP8.5 scenario) annual regional maximum wave heights, and of the available fetch. It includes an estimate of the possible future increase in regional maximum winds over widening ice-free areas in the Arctic. The ocean waves were simulated using the WAVEWATCH III wave model driven by surface winds and sea ice concentrations as simulated by five global climate models that participated in the Coupled Climate Model Comparison Phase 5 (CMIP5) project for both the historical and future periods.
