temp_geom function

Calculate geometrical temperature trend

Calculate geometrical temperature trend

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

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.

Returns

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