Calculates the Gorczynski continentality index using instance data. Tmax is July average temp, Tmin is January average temp. :returns: Continentality index C. :rtype: float

Raises:

ValueError – If July or January temperatures are not set in the instance.

Munin.Geo.Temperature.Odin_1983.Odin_temperature_sum(latitude: float, altitude_m: float) → float[source]

Estimate annual temperature sum above 5°C.

This function calculates the annual temperature sum (in degree-days) above 5 degrees Celsius based on latitude and altitude. It uses an empirical model developed by Odin, Eriksson, and Perttu (1983).

Source:

Odin, Eriksson & Perttu (1983). “Temperature Climate Maps for Swedish Forestry.” Reports in Forest Ecology and Forest Soils, 45, p.45.

Parameters:

  • latitude (float) – Decimal latitude (degrees north).

  • altitude_m (float) – Altitude in meters above sea level.

Returns:

Estimated annual temperature sum > 5 degrees Celsius.

Return type:

float
