In ConSciR: Tools for Conservation Science

Adjust Humidity and add RH zones

Description

This function processes a dataframe with temperature and relative humidity data and classifies the data into climate control zones. It generates adjusted temperature and humidity values based on thresholds.

Usage

add_humidity_adjustments(
  mydata,
  Temp = "Temp",
  RH = "RH",
  LowT = 16,
  HighT = 25,
  LowRH = 40,
  HighRH = 60,
  P_atm = 1013.25,
  ...
)

Arguments

mydata	A dataframe containing temperature and relative humidity data.
Temp	Character string name of the temperature column (default "Temp").
RH	Character string name of the relative humidity column (default "RH").
LowT	Numeric lower temperature threshold (default 16).
HighT	Numeric higher temperature threshold (default 25).
LowRH	Numeric lower relative humidity threshold (default 40).
HighRH	Numeric higher relative humidity threshold (default 60).
P_atm	Atmospheric pressure in kPa or hPa (currently unused, default 1013.25).
...	Additional arguments passed to internal calculation functions.

Value

The input dataframe augmented with multiple humidity and temperature adjustment columns.

AH

Absolute Humidity (g/m³): The mass of water vapor per unit volume of air.

DP

Dew Point (°C): The temperature at which air becomes saturated and water vapor condenses.

zone

Categorical variable defining climate control actions based on temperature and RH: 'Heating only', 'Dehum or heating', 'Cooling and hum', etc.

TRH_zone

Temperature-relative humidity category: 'Hot', 'Cold', 'Dry', 'Hot and humid', etc.

T_zone

Temperature zone classification: 'Cold', 'Within', or 'Hot'.

RH_zone

Relative humidity zone classification: 'Dry', 'Within', or 'Humid'.

dTemp

Temperature difference from specified thresholds (°C), indicating required heating or cooling.

dRH

Relative humidity difference from specified thresholds (%), indicating humidification or dehumidification.

newTemp_TRHadj

Adjusted temperature (°C) after applying temperature and relative humidity correction based on zone.

newAH_TRHadj

Adjusted absolute humidity (g/m³).

newRH_TRHadj

Adjusted relative humidity (%) reflecting new temperature and absolute humidity.

dTemp_TRHadj, dAH_TRHadj, dRH_TRHadj

Differences between adjusted and original temperature, absolute humidity, and relative humidity respectively.

newTemp_AHadj, newAH_AHadj, newRH_AHadj

Adjustments based on absolute humidity only (i.e. dehumidification or humidification).

newTemp_Tadj, newRH_Tadj, newAH_Tadj

Adjustments based on temperature only (i.e. heating or cooling).
