[awips_install.sh --cave ](https://www.unidata.ucar.edu/software/awips2/awips_install.sh)

For CentOS/Red Hat 6 and 7. Installs to /awips2/cave and writes files to ~/caveData.

sudo ./awips_install.sh --cave

Run CAVE from the Linux Desktop menu Applications > Internet > AWIPS CAVE, or from the command line as simply `cave`.

System Requirements

You can reset CAVE at any time by removing the **~/caveData** directory (on macOS **~/Library/caveData**) and reconnecting to an EDEX server.

Download and install both
[awips-cave.dmg ](https://www.unidata.ucar.edu/downloads/awips2/awips-cave.dmg)
[awips-python.pkg ](https://www.unidata.ucar.edu/downloads/awips2/awips-python.pkg)

**Supported Graphics Devices for macOS**

  • Intel HD Graphics
  • Intel Iris
  • NVIDIA GeForce

    • **Unsupported Graphics Devices for macOS**

  • AMD Radeon R9
  • AMD Radeon Pro
  • AMD FirePro D300

    • Writes and syncs files to ~/Library/caveData.

    **awips-python.pkg** is not a prerequisite, and CAVE will still run and display data without it, but to use any derived parameter functions such as wind barbs/arrows and grid parameters on various vertical coordinates, jep must be installed in some way (it is assumed in /Library/Python/2.7/site-packages/jep/)

    | ## Windows | | | |:----------------------------------------:|:--| |

    |

    [awips-cave.msi ](https://www.unidata.ucar.edu/downloads/awips2/awips-cave.msi)

    Writes files to **~/caveData** (in your user home directory)

    Requires Python 3, Numpy, and Jep be installed

    Requires **PYTHONHOME** be defined

    In addition to the application directory, the MSI installer will attempt to copy the *[gridslice](https://github.com/mjames-upc/gridslice)* shared library to `$PYTHONHOME/Dlls`. If the `$PYTHONHOME` environmental variable is not defined, *gridslice* will not be installed. You can always rerun the installer after defining `$PYTHONHOME` and then check that the file `gridslice.pyd` is installed in `$PYTHONHOME/Dlls`.

    CAVE will still run without gridslice, but certain bundles which use derived parameters, such as [isentropic analyses](../cave/d2d-grids/#isentopic-analysis-270k-320k), will not load.

    --- ## AWIPS Data in the Cloud Unidata and XSEDE Jetstream have partnered to offer a EDEX data server in the cloud, open to the Unidata university community. Select the server in the Connectivity Preferences dialog, or enter **`edex-cloud.unidata.ucar.edu`** (without *http://* before, or *:9581/services* after). ![EDEX in the cloud](../images/boEbFSf28t.gif) --- ## caveData Directory After connecting to an EDEX server, you will have a local directory named **caveData** which contains files synced from EDEX as well as a client-side cache for data and map resources. You can reset CAVE by removing the **caveData** directory and reconnecting to an EDEX server. Your local files have been removed, but if you are re-connecting to an EDEX server you have used before, the remote files will sync again to your local **~/caveData** (bundles, colormaps, etc.). * Linux: `/home//caveData` * macOS: `/Users//Library/caveData` * Windows: `C:\Users\\caveData`
