RUFAS.current_day_conditions module

class RUFAS.current_day_conditions.CurrentDayConditions(incoming_light: float, min_air_temperature: float, mean_air_temperature: float, max_air_temperature: float, daylength: float | None = None, annual_mean_air_temperature: float | None = None, snowfall: float = 0.0, rainfall: float = 0.0, irrigation: float = 0.0, precipitation: float = 0.0)

Bases: object

The purpose of this class is to combine and covert infos from weather data and field data and creates a current weather class that have all the needed attributes to allow field and field manager to work properly.

Attributes

incoming_light: float

Incoming light radiation energy (MJ/m^2).

min_air_temperature: float

Minimum air temperature for the day (C).

mean_air_temperature: float

Average air temperature for the day (C).

max_air_temperature: float

Maximum air temperature for the day (C).

daylength: float, optional, default=None

Length of time from sunup to sundown on the day (hours).

annual_mean_air_temperature: float, optional, default=None

Average annual air temperature for the year (C).

snowfall: float, default=0.0

Amount of snow that falls on the day (mm).

rainfall: float, default=0.0

Amount of rainfall that occurs on the day (mm).

irrigation: float, default=0.0

Amount of irrigation that is applied to the field on that day (mm).

precipitation: float, default=0.0

Amount of precipitation that occurs on the day (mm).

Notes

_deg_trig and _determine_daylength are more of temporary methods that approximately estimates the day length, this will be revisited for a more accurate implementation post v1

Returns

float

The length of the current day (hours).
