File Naming

<Catchment>_CemaNeigeInfo.csv

Example: Au Saumon_CemaNeigeInfo.csv

Format

Key-value pairs in CSV format (no header row).

Required Keys

Key Description Units
QNBV Mean annual solid precipitation mm/year
AltiBand Altitude band boundaries m (semicolon-separated)
Z50 Median catchment altitude m
Lat Catchment latitude degrees

Example

QNBV,354.9
AltiBand,379;433;474;532;672
Z50,474
Lat,45.482

Notes

  • AltiBand values define the boundaries of elevation bands, separated by semicolons
  • The number of altitude layers is determined by the number of values in AltiBand
  • QNBV (Quantité de Neige du Bassin Versant) represents average annual snowfall
  • Z50 is the median elevation, used for temperature lapse rate calculations
  • Lat (latitude) is used for day length calculations in the snow model
