[BUG] undefined variables

[garlic-os]

Describe the bug flake8 found some places where a variable is referred to but never defined (flake8 F821). This issue lists those places so we can figure out what's gone wrong.
An interesting thing to note is if runtime errors have never been encountered for these variables, then the code they live in has never been reached.

Uses of undefined variables

• test.test_util.py:339 - read_wm_file
• tools.RAiDER.processWM.py:179 - make_weather_model_filename
• tools.RAiDER.models.template.py:102 - z
