Reduce Model Output Size - Limit output to specified columns of interest

[fbaig]

Problem
Working with AORC dataset, the output generated by the model is very large (GBs). Pulling output back to the user environment can become prohibitive and limit further analysis.

Proposed Solution
Generally, a user is interested in a specific category of columns instead of all of the columns. Limit the number of columns generated by the model. For example, selecting only streamflow columns from CHROUT reduces the output size by approximately 65%

Possible implementations

• Customize postprocessing.sh to filter out columns of interest only
• Look for possible parameters in the WRF-Hydro model itself to generate only specified columns
