Description
This dataset contains selected variables as monthly means, extracted from the original The Community Earth System Model 2 (CESM2) Large Ensemble Community Project (LENS2) dataset. Additionally, it contains observational reference datasets for the respective variables. The data in this bucket is lossy compressed with zfp. We provide full ensembles with 100 members for the variables listed in the table below. The 3d winds and temperature (ua, va, ta) are provided at preassure levels 200 and 850 hPa. Specific humidity is provided at levels 300 and 850 hPa. The full set comprises 4 repositories:
- LENS2 data repository (1960-1990) (DOI: 10.5281/zenodo.15049672)
- LENS2 data repository (1990-2014) (DOI: 10.5281/zenodo.15045356)
- LENS2 data repository (1859-1880) (DOI: 10.5281/zenodo.15049720)
- Script repository (DOI: 10.5281/zenodo.15052431)
How to extract and use the data is described in the README of the script repository. For questions, please email to kai.keller@bsc.es and marta.alerany@bsc.es.
The LENS2 project provides open access to multi-decadal climate simulation data at 1-degree horizontal resolution, conducted with a large ensemble comprising 100
members (Rodgers et al., 2021). The simulation covers a historical period (1850-2014) and a future projection (2015-2100), following the Shared Socioeconomic Pathways (SSP) scenario SSP3-7.0.
For a full description of the dataset, we refer to the webpage of the LENS2 project: https://www.cesm.ucar.edu/community-projects/lens2, and to the article from Rodgers et al., 2021 (DOI: 10.5194/esd-12-1393-2021).
