R Documentation

Calculate geometrical temperature trend

Description

Calculate geometrical temperature trend for mean, minimum or maximum temperature.

Usage

temp_geom(day,
          fi,
          variable="mean",
          ab = NULL)

Arguments

`day`	integer; Day of the year (from 1 to 366). Single value or vector of days of the year (only if `fi` is single value).
`fi`	numeric; Latitude. Single value or vector of latitudes (only if `day` is single value).
`variable`	character; Geometrical temperature trend calculated for mean, minimum or maximum temperature; Possible values are `'mean'`, `'min'` or `'max'`. `'mean'` is default.
`ab`	Predefined coefficients to be used instead of incorporated.

Value

A numerical single value or vector with calculated geometrical temperature trend.

Examples

          fi = 45.33,
          variable="mean")
          
tgeom_vect <- temp_geom(day = 1:365,
          fi = 45.33,
          variable="mean")
          
tgeom_vect2 <- temp_geom(day = 1,
          fi = seq(35, 45, 0.5),
          variable="mean")
