Decisions

  • • Missing month ≠ dry month
  • • Flag, don't delete
  • • climatol only changes measured values where it finds a break

Checks

  • • At least 48 months to infill
  • • inht only from the exploratory run
  • • Before/after, same months

Raster validation

  • • LOOCV and 25–100 km exclusion
  • • ANUSPLIN: same model, same cells
  • • Plausibility: 1.5 × measured maximum
