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.
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
The easiest way to install CDO is using Homebrew:
brew install cdo
More information can be found on the CDO Mac Website.
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:
sudo apt-get upgrade
sudo apt-get install cdo
More information can be found on the CDO Windows Website
sudo apt-get upgrade
sudo apt-get install cdo
You can install the development version of hotrstuff from GitHub with:
# install.packages("devtools")
devtools::install_github("SnBuenafe/hotrstuff")To get started with hotrstuff, follow the vignette
