Surface wind and sea ice with high resolution for ssp245 and ssp585 scenarios

[NadiaE]

Hi all,
We are modeling wave activity near several coastal settlements under historical and projected future climate conditions.
As part of this work, I am interested in using the ssp245 and ssp585 climate scenarios based on the CESM2 model.
Specifically, I am looking for vector components of near-surface wind — that is, the northward and eastward 10 m wind speed components (uas and vas) — for the period from nowadays to 2100.
Ideally, the dataset would have:

• Temporal resolution: less than 1 day (preferably 3–6 hours)
• Spatial resolution: approximately 0.5° (~50 km) or finer
• Region of interest: the Alaskan coast

I've found just more rough data, or surface wind without directions, but unfortunately, it is insufficient for our goals.
Does anyone know if such data is available somewhere? Or maybe which approach would you recommend to get surface wind with such resolution from existing data?
Also, we need sea ice data with same spatial resolution, but 1 point/day would be great.

Many thanks!
Nadia

As I mentioned in my email to you, CESM does provide 6-hourly wind components for the SSP scenarios via our CMIP6 submission, for example

ESGF MetaGrid

Web site created using create-react-app

aims2.llnl.gov

but you will have to interpolate to the near-surface to get the values you want.

Also, the spatial resolution is approximately 1 degree, but you can also interpolate to a finer grid and subset the geographic region of interest.

Dear Gary,
Thank you for your answer!
Unfortunately, such downscaling turns out to be too coarse for our tasks. We'll keep looking for a solution to the problem.
Thank you!
