There is a new product up on Copernicus with floe size distribution derived from Sentinel-1 SAR imagery and passive microwave.

There is a long dataset with good coverage in the Arctic:

> **[Copernicus Marine MyOcean Viewer](https://data.marine.copernicus.eu/viewer/expert?view=dataset&dataset=SEAICE_ARC_PHY_AUTO_L3_MYNRT_011_023)**
>
> Welcome to the Copernicus Marine Service "MyOcean" Viewer.

And they have processed what they can in the Antarctic but its limited both in time (only 2 years) and looks like it has spatial gaps.

Could be useful datasets for validatining sea-ice+wave models , including marginal ice zone width and floe size validation 🙂

Thanks Anton! This sounds exciting and I’ll definitely be looking into these products in the coming weeks.

@adfraser is better at reading than I am and pointed out the Antarctic Sea Ice information is only concentration derived from SAR, doesn’t included the floe size
