5.2.1.1. MODE: CESM and GPCP Asian Monsoon Precipitation¶
model_applications/climate/MODE_fcstCESM_obsGPCP_AsianMonsoonPrecip.conf
Scientific Objective¶
To evaluate the CESM model daily precipitation against the GPCP daily precipitation over the Indian Monsoon region to obtain object based output statistics. This was developed as part of the NCAR System for Integrated Modeling of the Atmosphere (SIMA) project.
Datasets¶
Forecast dataset: CESM Daily Precipitation
Observation dataset: GPCP Daily Precipitation
METplus Components¶
This use case runs mode to create object based statistics on daily precipitation data from the CESM model and observations from the GPCP.
METplus Workflow¶
The mode tool is run for each time. This example loops by model initialization time. It processes 4 valid times, listed below.
METplus Configuration¶
METplus first loads all of the configuration files found in parm/metplus_config, then it loads any configuration files passed to METplus via the command line with the -c option, i.e. -c parm/use_cases/model_applications/climate/MODE_fcstCESM_obsGPCP_AsianMonsoonPrecip.conf

MET Configuration¶
METplus sets environment variables based on the values in the METplus configuration file. These variables are referenced in the MET configuration file. YOU SHOULD NOT SET ANY OF THESE ENVIRONMENT VARIABLES YOURSELF! THEY WILL BE OVERWRITTEN BY METPLUS WHEN IT CALLS THE MET TOOLS! If there is a setting in the MET configuration file that is not controlled by an environment variable, you can add additional environment variables to be set only within the METplus environment using the [user_env_vars] section of the METplus configuration files. See the ‘User Defined Config’ section on the ‘System Configuration’ page of the METplus User’s Guide for more information.

Running METplus¶
This use case can be run two ways:
Passing in MODE_fcstCESM_obsGPCP_ConusPrecip.conf then a user-specific system configuration file:
master_metplus.py -c /path/to/METplus/parm/use_cases/model_applications/climate/MODE_fcstCESM_obsGPCP_AsianMonsoonPrecip.conf -c /path/to/user_system.conf
Modifying the configurations in parm/metplus_config, then passing in MODE_fcstCESM_obsGPCP_AsianMonsoonPrecip.conf:
master_metplus.py -c /path/to/METplus/parm/use_cases/model_applications/climate/MODE_fcstCESM_obsGPCP_AsianMonsoonPrecip.conf
The former method is recommended. Whether you add them to a user-specific configuration file or modify the metplus_config files, the following variables must be set correctly:
INPUT_BASE - Path to directory where sample data tarballs are unpacked (See Datasets section to obtain tarballs). This is not required to run METplus, but it is required to run the examples in parm/use_cases
OUTPUT_BASE - Path where METplus output will be written. This must be in a location where you have write permissions
MET_INSTALL_DIR - Path to location where MET is installed locally
Example User Configuration File:
[dir]
INPUT_BASE = /path/to/sample/input/data
OUTPUT_BASE = /path/to/output/dir
MET_INSTALL_DIR = /path/to/met-X.Y
NOTE: All of these items must be found under the [dir] section.
Expected Output¶
A successful run will output the following both to the screen and to the logfile:
INFO: METplus has successfully finished running.
Refer to the value set for OUTPUT_BASE to find where the output data was generated. Output for this use case will be found in model_applications/climate/CESM_MODE (relative to OUTPUT_BASE) and will contain the following files:
