R: Creates a table of mean monthly "daily thermal range" (dtr)

Mo.Th.Ra.

R Documentation

Creates a table of mean monthly "daily thermal range" (dtr)

Description

Creates a table of mean monthly DTR (difference between maximum and minimum temperature) over the series' period, to use a reference for establishing the exponent "z" of the night stretch of the interpolation curve.

Usage

  Mo.Th.Ra.(Tmin, Tmax, name, min_mo.length = 21,
    silent = FALSE)

Arguments

`Tmin`	a table of 4 named columns, the first are year, month, day, the 4th is minimum temperature. The column names "month" and "T" are mandatory
`Tmax`	same for Tmax
`name`	name of the series dtr is calculated for
`min_mo.length`	minimum number of days necessary to calculate monthly dtr values
`silent`	logical. If `TRUE` no warning is issued

Value

A vector of 12 dtr values (1 for January, ... 12 for December)

Examples

data(Trentino_hourly_T)
id<-"T0001"
Tmin<-data.frame(Tn[,1:3], T=Tn[,id])
Tmax<-data.frame(Tx[,1:3], T=Tx[,id])
dtr <- Mo.Th.Ra.(Tmin = Tmin, Tmax = Tmax, name = id)
