Multi-Case Example Diagnostic Documentation¶
Last update: Oct 2022
This POD illustrates how multiple cases (experiments) can be analyzed together. The muliple cases are specified to the MDTF Framework where they are initialized and preprocessed independently.
This POD assumes familiarity with the single-case example diagnostic

The MDTF framework is distributed under the LGPLv3 license (see LICENSE.txt). Unless you’ve distributed your script elsewhere, you don’t need to change this.
The framework generates yaml file called case_info.yml with environment variables for the file paths and variable information for each case. The example_multicase POD reads the yaml file information into a dictionary, and loops through the dictionary to read near-surface air temperature (TAS) data for each case. The POD time averages the data and calculates the anomaly relative to the global mean. The anomalies are zonally-averaged and the results from all cases are shown on a single plot.
Required programming language and libraries¶
Python >= 3.7
Required model output variables¶
tas - Surface (2-m) air temperature (CF: air_temperature)
