The goal of hotrstuff is to facilitate the rapid download, wrangling and processing of Earth System Model (ESM) output from the Coupled Model Intercomparison Project (CMIP).
To get started, you will need to download the wget scripts from your chosen CMIP6 repository. We use: https://aims2.llnl.gov/search. From there hotrstuff makes it easy to:
- Download,
- Merge files,
- Regrid to chosen resolution,
- Slice to required timeframe,
- Crop to requested spatial area,
- Create mean/median ensembles of variables, scenarios etc.
Requirements
hotrstuff requires the Climate Data Operators (CDO) software to be installed prior to use. The CDO software is a collection of many operators for standard processing of climate and forecast model data. The operators include simple statistical and arithmetic functions, data selection and subsampling tools, and spatial interpolation. hotrstuff leverages the power of CDO, within the R environment.
More about CDO installation can be found on the CDO installer website
Mac
The easiest way to install CDO is using Homebrew:
More information can be found on the CDO Mac Website.
Windows
Recent versions of Windows (>=10) included an Ubuntu embedded Linux. This environment offers a clean integration with the windows file systems and and the opportunity to install CDO via the native package manager of Ubuntu:
