• 10.1. Quality Assurance Checks for Successful CMAQ Run on CycleCloud
  • 10.1.1. run m3diff to compare the output data for two runs that have different values for NPCOL
  • 10.1.2. If CMAQ were compiled with -march=native, then you would see differences in the output if NPCOL was different, see previous version of this tutorial for more information
• 10.2. R analysis scripts
  • 10.2.1. Run the following R script to create box plots and spatial plots showing difference between two CMAQ runs.
• 10.3. Jupyter Notebook
  • 10.3.1. Use Jupyter Notebook to plot the daily average of O3 and NO2.
  • 10.3.2. Use Jupyter Notebook to plot the averges, average differences difference and average percent differences
