[Feature]: Refactor PMP CDP usage to remove ESGF output viewer package #1339
Description
Is your feature request related to a problem?
CDP depends on ESGF output viewer package that is no longer maintained. CDP is a framework for creating new climate diagnostic packages in a generalized manner – can be considered as a precursor of CMEC. It is a lightweight interface built on top of Python argparse allowing for a python script to serve as a parameter input at the command line.
Describe the solution you'd like
Several PMP metrics' drivers depend on CDP to use a parameter file in combination with overwriting some parameters from the command line parser. E.g.: mean_climate_driver.py -p basic_param.py --case_id 'Ex2' --regrid_tool 'xesmf’
The drivers are using parts of CDP that do not depend on ESGF output viewer. I propose copying only necessary scripts that do not depend on ESGF output viewer from CDP to PMP and then reference these in the drivers.
Describe alternatives you've considered
Research the functionality of ESGF output viewer/CDP to see if modern argparse or optparse can handle.
