GCAM for CDR Policy Deployment Documentation

Setup Instructions

Instance Requirements:

• r5a.4xlarge (for full capabilities) with 45GB of disk space
• m5a.2xlarge (for build capabilities only)

1. Turn on instance and ssh into instance.

2. git clone https://github.com/ecwood/GCAM-CDR-modeling.git

3. cd GCAM-CDR-modeling

4. screen -S setup_gcam

5. ./setup_gcam.sh > ~/setup_gcam.log 2>&1

6. Ctrl-A, Ctrl-D

GCAM Basics

Important GCAM Repositories:

• gcam-core
  • Full repository for GCAM
• gcam-doc
  • GitHub backend for official documentation
  • Acts as a searchable options for documentation
• gcamdata
  • Contains the data system for GCAM
  • This includes all of the CSV files and R scripts to compile the GCAM XML files

Running GCAM Scenarios

• Process GCAM Output

  Runtimes:

  • From scratch: ~17 minutes
  • From pickle file: ~2 minutes

Assorted Notes

• Can change time frame of scenario in modeltime.xml, theoretically, but I haven't gotten it to work, giving errors like this:

  ERROR:Invalid year: 2060 passed to Modeltime::getyr_to_per. 
  ERROR:Invalid year: 2065 passed to Modeltime::getyr_to_per. 
  ERROR:Invalid year: 2070 passed to Modeltime::getyr_to_per. 
  ERROR:Invalid year: 2075 passed to Modeltime::getyr_to_per. 
  ERROR:Invalid year: 2080 passed to Modeltime::getyr_to_per. 
  ERROR:Invalid year: 2085 passed to Modeltime::getyr_to_per. 
  ERROR:Invalid year: 2090 passed to Modeltime::getyr_to_per. 
  ERROR:Invalid year: 2095 passed to Modeltime::getyr_to_per. 
  ERROR:Invalid year: 2100 passed to Modeltime::getyr_to_per. 

Implementing H.R. 7434

Things I've tried:

1. 6969631 (fixed the DAC output value to exactly H.R. 7434 levels; worked, but not robust enough for what I need)
2. daf4ace (didn't do anything)
3. 57ad277 (didn't do anything)
4. Put in carbon_tax_20_5.xml in the policy spot (didn't do anything)

5. Adding these lines to the configuration file and reverting

   
   -                 <Value name="policy-target-file">../input/policy/carbon_tax_20_5.xml</Value>
   +                <Value name="policy-target-file">../input/policy/forcing_target_4p5.xml</Value>

  - What is a dispatch?

  Period 19: 2090 Model solved normally. Iterations period 19: 176. Total iterations: 15148

Period 20: 2095 Model solved normally. Iterations period 20: 283. Total iterations: 15431

Period 21: 2100 Model solved normally. Iterations period 21: 158. Total iterations: 15589

All model periods solved correctly. Model run completed. Policy Target Runner: scenario dispatch #3

Starting a model run. Running period 21 Model run beginning. Period 6: 2025 Model solved normally. Iterations period 6: 558. Total iterations: 16146
