MDTF-diagnostics: A Portable Framework for Weather and Climate Model Data Analysis

The MDTF-diagnostics package is a portable framework for running process-oriented diagnostics (PODs) on weather and climate model data.

What is a POD?

Each process-oriented diagnostic [POD; Maloney et al.(2019)] targets a specific physical process or emergent behavior to determine how well one or more models represent the process, ensure that models produce the right answers for the right reasons, and identify gaps in the understanding of phenomena. Each POD is independent of other PODs. PODs generate diagnostic figures that can be viewed as an html file using a web browser.

Available Diagnostics

The links in the table below show sample output, a brief description, and a link to the full documentation for each currently-supported POD.

Quickstart installation instructions

See the documentation site for all other information, including more in-depth installation instructions.

Visit the GFDL Youtube Channel for tutorials on package installation and other MDTF-diagnostics-related topics

Prerequisites

Anaconda3, Miniconda3, or micromamba.
Installation instructions are available here.
MDTF-diagnositics is developed for macOS and Linux systems. The package has been tested on, but is not fully supported for, the Windows Subsystem for Linux.
Attention macOS M-series chip users: the MDTF-diagnostics base and python3 conda environments will only build with micromamba on machines running Apple M-series chips. The NCL and R environments will NOT build on M-series machines because the conda packages do not support them at this time.

Notes

$ indicates strings to be substituted, e.g., the string $CODE_ROOT should be substituted by the actual path to the MDTF-diagnostics directory.
Consult the Getting started section to learn how to run the framework on your own data and configure general settings.
POD contributors can consult the Developer Cheatsheet for brief instructions and useful tips

1. Install MDTF-diagnostics

Open a terminal and create a directory named mdtf, then $ cd mdtf
Clone your fork of the MDTF repo on your machine: git clone https://github.com/[your fork name]/MDTF-diagnostics
Check out the latest official release: git checkout tags/[version name]
Run % conda info --base to determine the location of your Conda installation. This path will be referred to as $CONDA_ROOT.
cd $CODE_ROOT, then run

ANACONADA/MINICONDA

% ./src/conda/conda_env_setup.sh --all --conda_root $CONDA_ROOT --env_dir $CONDA_ENV_DIR

MICROMAMBA on machines that do NOT have Apple M-series chips

% ./src/conda/micromamba_env_setup.sh --all --micromamba_root $MICROMAMBA_ROOT --micromamba_exe $MICROMAMBA_EXE --env_dir $CONDA_ENV_DIR

MICROMAMBA on machines with Apple M-series chips

% ./src/conda/micromamba_env_setup.sh -e base --micromamba_root $MICROMAMBA_ROOT --micromamba_exe $MICROMAMBA_EXE --env_dir $CONDA_ENV_DIR

% ./src/conda/micromamba_env_setup.sh -e python3_base --micromamba_root $MICROMAMBA_ROOT --micromamba_exe $MICROMAMBA_EXE --env_dir $CONDA_ENV_DIR

Substitute the actual paths for $CODE_ROOT, $CONDA_ROOT, $MICROMAMBA_ROOT, MICROMAMBA_EXE, and $CONDA_ENV_DIR.
$MICROMAMBA_ROOT is the path to micromamba installation on your system (e.g., /home/${USER}/micromamba). This is defined by the $MAMBA_ROOT_PREFIX environment variable on your system when micromamba is installed
$MICROMAMBA_EXE is full path to the micromamba executable on your system (e.g., /home/${USER}/.local/bin/micromamba). This is defined by the MAMBA_EXE environment variable on your system
All flags noted for your system above must be supplied for the script to work.

NOTE: The micromamba environments may differ from the conda environments because of package compatibility discrepancies between solvers

% ./src/conda/micromamba_env_setup.sh --all --micromamba_root $MICROMAMBA_ROOT --micromamba_exe $MICROMAMBA_EXE --env_dir $CONDA_ENV_DIR builds the base environment, NCL_base environment, and a limited version of the python3_base enviroment that excludes the following packages and dependencies that may be required by the POD(s) you want to run:

falwa
gridfill

2. Download the sample data

Supporting observational data and sample model data are available via anonymous FTP at ftp://ftp.cgd.ucar.edu/archive/mdtf.

Digested observational data: run wget ftp://ftp.cgd.ucar.edu/archive/mdtf/obs_data_latest/\* or download the collection "NCAR CGD Anon" from Globus
NCAR-CESM-CAM sample data (12.3 Gb): model.QBOi.EXP1.AMIP.001.tar (ftp://ftp.cgd.ucar.edu/archive/mdtf/model.QBOi.EXP1.AMIP.001.tar)
NOAA-GFDL-CM4 sample data (4.8 Gb): model.GFDL.CM4.c96L32.am4g10r8.tar (ftp://ftp.cgd.ucar.edu/archive/mdtf/model.GFDL.CM4.c96L32.am4g10r8.tar)

Note that the above paths are symlinks to the most recent versions of the data and will be reported as zero bytes in an FTP client.

Running tar -xvf [filename].tar will extract the contents in the following hierarchy under the mdtf directory:

mdtf
 ├── MDTF-diagnostics
 ├── inputdata
     ├── model
     │   ├── GFDL.CM4.c96L32.am4g10r8
     │   │   └── day
     │   │       ├── GFDL.CM4.c96L32.am4g10r8.precip.day.nc
     │   │       └── (... other .nc files )
     │   └── QBOi.EXP1.AMIP.001
     │       ├── 1hr
     │       │   ├── QBOi.EXP1.AMIP.001.PRECT.1hr.nc
     │       │   └── (... other .nc files )
     │       ├── 3hr
     │       │   └── QBOi.EXP1.AMIP.001.PRECT.3hr.nc
     │       ├── day
     │       │   ├── QBOi.EXP1.AMIP.001.FLUT.day.nc
     │       │   └── (... other .nc files )
     │       └── mon
     │           ├── QBOi.EXP1.AMIP.001.PS.mon.nc
     │           └── (... other .nc files )
     └── obs_data ( = $OBS_DATA_ROOT)
         ├── (... supporting data for individual PODs )

The default test case uses the QBOi.EXP1.AMIP.001 sample data. The GFDL.CM4.c96L32.am4g10r8 sample data is only needed to test the MJO Propagation and Amplitude POD.

You can put the observational data and model output in different locations (e.g., for space reasons) by changing the values of OBS_DATA_ROOTas described below in section 3.

3. Generate a data catalog for the sample input data

The MDTF-diagnostics package provides a basic catalog generator to assist users with building data catalogs in the tools/catalog_builder directory

4. Configure framework paths

The MDTF framework supports setting configuration options in a file as well as on the command line. An example of the configuration file format is provided at templates/runtime_config.[jsonc | yml]. We recommend configuring the following settings by editing a copy of this file.

CATALOG_DIR: path to the ESM-intake data catalog
If you've saved the supporting data in the directory structure described in section 2, and use observational input data the default value for OBS_DATA_ROOT (../inputdata/obs_data) will be correct. If you put the data in a different location, the path should be changed accordingly.
WORK_DIR is used as a scratch location for files generated by the PODs, and should have sufficient quota to handle the full set of model variables you plan to analyze. This includes the sample model and observational data (approx. 19 GB) PLUS data required for the POD(s) you are developing.** No files are saved here unless you set OUTPUT_DIR to the same location as WORK_DIR, so a temporary directory would be a good choice.
OUTPUT_DIR should be set to the desired location for output files. OUTPUT_DIR and WORK_DIR are set to the same locations by default. The output of each run of the framework will be saved in a different subdirectory in this location. As with the WORK_DIR, ensure that OUTPUT_DIR has sufficient space for all POD output.
conda_root should be set to the value of $CONDA_ROOT used in section 2.
Likewise, set conda_env_root to the same location as $CONDA_ENV_DIR in section 2

We recommend using absolute paths in runtime_config.[jsonc | yml], but relative paths are also allowed and should be relative to $CODE_ROOT.$CODE_ROOT contains the following subdirectories:

diagnostics/: directory containing source code and documentation of individual PODs
doc/: directory containing documentation (a local mirror of the documentation site)
src/: source code of the framework itself
submodules/: location to place 3rd-party submodules to run as part of the MDTF-diagnostics workflow
tests/: unit tests for the framework
templates/: runtime configuration template files
tools/: helper scripts for building ESM-intake catalogs, and other utilities
user_scripts/: directory where users can place custom preprocessing scripts

5. Run the framework

The framework runs PODs that analyze one or more model datasets (cases), along with optional observational datasets, using. To run the framework on the example_multicase POD, modify the example configuration file and run

cd $CODE_ROOT
./mdtf -f templates/[runtime_config.[jsonc | yml]

The above command will execute PODs included in pod_list block of runtime_config.[jsonc | yml].

If you re-run the above command, the result will be written to another subdirectory under $OUTPUT_DIR, i.e., output files saved previously will not be overwritten unless you change overwrite in the configuration file to true.

The output files for the test case will be written to $OUTPUT_DIR/MDTF_Output/. When the framework is finished, open $OUTPUT_DIR/MDTF_Output/[POD NAME]/index.html in a web browser to view the output report.

You can specify your own datasets in the caselist block of the runtime config file and provide a catalog with the model data, or run the example_multicase POD on the synthetic data and associated test catalog specified in the configuration file. To generate the synthetic CMIP data, run:

mamba env create --force -q -f ./src/conda/_env_synthetic_data.yml
conda activate _MDTF_synthetic_data
pip install mdtf-test-data
mkdir mdtf_test_data && cd mdtf_test_data
mdtf_synthetic.py -c CMIP --startyear 1980 --nyears 5
mdtf_synthetic.py -c CMIP --startyear 1985 --nyears 5

Then, modify the path entries in diagnostic/example_multicase/esm_catalog_CMIP_synthetic_r1i1p1f1_gr1.csv, and the "catalog_file": path in diagnostic/example_multicase/esm_catalog_CMIP_synthetic_r1i1p1f1_gr1.json to include the root directory locations on your file system. Full paths must be specified.

Depending on the POD(s) you run, the size of your input datasets, and your system hardware, run time may be 10--20 minutes.
