Why did they target 1.2km instead of 1? Or any other number?

I guess best ask the authors.

> Our ICON-ESM configuration is already used in production mode for scientific purpose with horizontal resolutions of 10 km, 5 km and 2.5 km. With the 1.2 km configuration we have now opened the door for a new class of numerical models which will allow us to investigate local impacts of climate change, such as extremes of precipitation, storms and droughts.

Some evidence of them using 10 km cells and then subdividing into halves, gets you down to 1.25 km.

The grid is not squared, is hexagonal, surely it relates to that.
