Living with bugs

  • MEDUSA
    • One bug before Christmas; 4 associated with MEDUSA code since (one bug was in NEMO code used by MEDUSA and didn't change result, but prevents NaNs in code)
  • NEMO
    • A bug found/fix every ~month
    • Latest involves runoff
  • UM
    • Some very fresh land surface code - always more comforting to use code that's been used for a while
    • For ~4 years, a bug which meant the wrong gas was being used in radiation absorption for all but first gas (O3).
