LES data

We are happy to share data from our simulations and we hope that they are useful to your work. All data are shared under the Creative Commons Attribution 4.0 International license. When using any material (i.e., data, images, etc.) obtained from our website or other computing resources, you agree to use the recommended data citation format. All material are provided “as is” without any express or implied warranties. If you have questions please contact us.

Data are transferred using Globus, an easy-to-use, high-performance data transfer tool. Globus can transfer the data between two Globus “Endpoints”. This means that you need to have access to an “Endpoint”. Several University or Laboratory computers clusters are already connected to Globus, so please check with your local expert. Fortunately, your personal computer can also become an Endpoint using “Globus Connect Personal,” thus, you can transfer the data directly to your workstation. 

Please provide your Globus user identity (typically an email address) when you fill out the data request form, and in a few days, we will email you the Endpoint and path to dataset.

Data format

The LES output is stored in NetCDF format. The model output is split into different NetCDF files. Each file contains all variables at a particular time for a sub-domain of the entire model domain. The full domain is split into M × N regions, or tiles, in the horizontal directions. The netCDF files contain information regarding the location of each of the sub-domains. 

An example Matlab script that joins the data from the sub-domain files and creates a single contiguous variable can be obtained from here.

An annotated version of the Matlab example, stitch, provides more details.


Currently, two datasets are available:

  • Precipitating Shallow Cumulus (RICO)
    Citation: Matheou, G. and D. Chung, 2014: Large-eddy simulation of stratified turbulence. Part II: Application of the stretched-vortex model to the atmospheric boundary layer, Journal of the Atmospheric Sciences, 71, 4439–4460.
  • Nocturnal Stratocumulus (DYCOMS II RF01)
    Citation: Matheou, G., 2018: Turbulence structure in a stratocumulus cloud, Atmosphere, 9, 392; doi:10.3390/atmos9100392

More details about the datasets are coming soon. Please contact us with any questions in the meantime…
