Amazing visualization of our recent sub-grid variability work by Michael Böttinger (DKRZ) 🤩.
It shows the local detail in global precipitation resolved by km-scale models. From 0:50 in direct comparison to CMIP6-type 100km. From 2:07 the sub-grid variability is shown. 🤓🧪

New paper in ERL! We study the importance of resolution for the representation of climate extremes.
We use a new generation of km-scale models to show that many important details about temperature and precipitation extremes are hidden at CMIP6-like resolutions.

The repository is hierarchical. Click on the rightmost tab, there you can select one of the two models, and then again one of the two resolutions. At the lowest level, there is a green 'Download' button.

We are working on related topics right now but I can't make any specific promises at this point.
Having said that: we have published all the data that go into our study as netCDF (thats annual extreme indices from 2021-2049)👇

We focus on a subset of the 27 ETCCDI climate extreme indices in the paper. But we have published the full set of ETCCDI indices with 10km resolution globally at the World Data Center for Climate here:
