C2SM provides a number of datasets (see below). In addition, the Forest Ecology group has put together information about commonly used datasets and how to use them here.

Datasets provided by C2SM

We provide different climate datasets such as CMIP5, CMIP6 or CORDEX, as downloaded from the original sources, as well as processed datasets such as the so-called CMIP6-NextGeneration (CMIP6-ng) archive. If you need access to other climate datasets contact us at request@c2sm.ethz.ch and we will try to help.

The table below shows an overview over the datasets we already provide.

(1) native means every model on their native grid they were run on

(2) CMIP-ng: Next Generation archives were maintained by Reto's group (Jan Sedlacek/Lukas Brunner)
Ruth Lorenz / C2SM took over cmip6-ng in 2022. contact: cmip6-archive@env.ethz.ch, documentation: https://doi.org/10.5281/zenodo.3734128
