To use the container at NCI:

module use /g/data/access/ngm/modules
module load envs/metplus/5.0

All MET commands and run_metplus.py will be available on PATH

Demonstration

The demo configurations available at METplus Use Cases can be run using the container.

  1. Download the sample data from https://dtcenter.ucar.edu/dfiles/code/METplus/METplus_Data/v5.0/sample_data-met_tool_wrapper-5.0.tgz and untar into a directory

  2. Create a configuration file local.conf containing the input and output paths

[dir]
INPUT_BASE=/path/to/metplus_inputs
OUTPUT_BASE=/path/to/outputs

  1. Save the demo configuration to a local file

  2. Run METplus passing it both local.conf and the demo configuration

run_metplus.py local.conf ASCII2NC.conf

Container Details

This package is provided as an Apptainer container. The container file is available at $METPLUS_ROOT/etc/image.sif, build configuration is at https://git.nci.org.au/bom/ngm/spack-environments.

Commands provided by the module can be run without needing any extra configuration. You can access the container internals with the imagerun command, e.g. imagerun ls / will show the container contents. imagerun shell will start a shell inside the container, once inside the shell run source /build/entrypoint.sh to load the environment.

Thoughts from someone who had never used this before:

ASCII2NC.conf can be found on their github: https://github.com/dtcenter/METplus/blob/main_v5.1/parm/use_cases/met_tool_wrapper/ASCII2NC/ASCII2NC.conf

INPUT_BASE is the folder containing the met_test folder (e.g. /g/data/<project>/<username>/, NOT /g/data/<project>/<username>/met_test)
OUTPUT_BASE is the folder where logs/outputs/etc go (e.g. /g/data/<project>/<username>/outputs)
