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. doi.org/10.1088/1748...
Very good!! The physically possible is what we must know and adapt to. Are there more papers in the pipeline from this effort? I mean, ones that don't again focus resolution but compare extremes in ICON and IFS 2020-2025 to those 2030-2035, 2040-2045 for example? And is a netCDF planned? Thank you!
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)👇 bsky.app/profile/luka...
Thank you! Rather keen on seeing your further explorations too! I checked that yesterday to see whether I can find netCDFs. But I still can't. Which of the blue-highlighted URLs is the download? Your zenodo repository holds only shell scripts – for which I'd need a data source too.
If you explore further, cd future papers include a clickable online map? You know, a click showing a particular's location calculated extremes. Akin to what vanWesten et al 2025 did for AMOC collapse (but sadly in a low resolution with "future extremes" at 2C already occurring in today's reality.)
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. Here's a direct link to the high-resolution IOCN results: www.wdc-climate.de/ui/entry?acr...
I think, now I get it, thank you very much. I'll give it a go once or if they give me access. One of my stupid questions is also whether SSP3-7.0 GMT in IFS in 2049 will be the same as in AR6 or if not, how much higher than in www.ipcc.ch/report/ar6/w... Would you like to do a spoiler for me? 🙏🙏🙏
Looks like really valuable work. Any conclusions about high-latitudes?
We calculate extreme indices from two ~10km models (ICON & IFS). From them we quantify what information is lost at CMIP6-like resolutions of ~100km. To do so we introduce the concepts of sub-grid variability and sub-grid anomaly. Details in the paper: iopscience.iop.org/article/10.1...
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: doi.org/10.26050/WDC...
The code we used to produce our figures is freely available under a permissive license. If you want to work with it and have any questions, feel free to reach out to me. There are also open master’s thesis projects on the topic! github.com/lukasbrunner...
An extensive database of plots for all ETCCDI climate extreme indices is also available under a CC BY license on Zenodo: doi.org/10.5281/zeno...
