Incorporating SSP5-8.5 Wind Projections into InVEST Coastal Model (WW3 Structure)

Software Support

Hi everyone!

I’m using the InVEST Coastal Vulnerability Model to run two different scenarios: one for the present and another for a future projection. I’d like to incorporate future-projected wind and wave data instead of relying solely on the default WaveWatch III (WW3) dataset. Although I wasn’t able to find projected wave data, I decided to at least include projected wind speed to make the future scenario more realistic.

To do this, I downloaded monthly near-surface wind speed data from the HadGEM3-GC31-MM (UK) model for the SSP5-8.5 scenario in the year 2070. I used monthly northward and eastward near-surface wind components from the same model, scenario, and year.

I’m now trying to figure out how to convert this data into a format compatible with the WW3 structure used in InVEST — specifically, how to distribute it into the 16 directional sectors.

Has anyone tried doing something similar? Any advice or guidance would be greatly appreciated!

Thank you in advance!
