Goal

  • Trying varying levels of bandwidth and DBL scaling with pre-fractionation abundances ('DBL-comm')
  • Varying parameters
    • bandwidth (bw)
      • 0.02, 0.2, 0.4, 0.6, 0.8
    • diffusive boundary layer (DBL) scaling (DBL scaling by abundance)
      • 0, 0.15, 0.2, 0.25, 0.3, 0.4, 0.8
  • NOTE: using default bandwidth for DBL & isotope incorporation steps
