hourly_RH: Estimation of the hourly relative humidity on a daily series

In Carm1r/fruclimadapt: Evaluation Tools for Assessing Climate Adaptation of Fruit Tree Species

Estimation of the hourly relative humidity on a daily series

Description

This function estimates the hourly relative humidity (RH), using daily temperature and humidity data. Hourly humidity is estimated with the formula proposed by Waichler and Wigmosta (2003) which require maximum and minimum values of daily temperature and relative humidity.

Usage

hourly_RH(climdata, lat)

Arguments

climdata	a dataframe with daily temperatures and RH for each day in a series. Must contain the columns Year, Month, Day, Tmax, Tmin, RHmax (daily maximum relative humidity) and RHmin (minimum daily relative humidity).
lat	the latitude of the site, in decimal degrees.

Value

dataframe with columns Date, Year, Month, Day, DOY, Hour, Temp and RH
