Variables

In some tests, such as SCT and FGT, two ranges of values have to be defined around each observation. The ranges of admissible and valid values (see ...).

Temperature (variable=T)

• Range of admissible values is observed value ± 20 °C
• Range of valid values is observed value ± 1 °C

Precipitation (variable=RR)

• General constraints
  • lower value have to be greater or equal to 0 mm
• Range of admissible values has:
  • lower value is the minimum value between (observed value - 10 mm) or (observed value - 0.5 * observed value)
  • higher value is the maximum value between (observed value + 10 mm) or (observed value + 0.5 * observed value)
• Range of valid values has:
  • lower value is the minimum value between (observed value - 1 mm) or (observed value - 0.1 * observed value)
  • higher value is the maximum value between (observed value + 1 mm) or (observed value + 0.1 * observed value)
