Description

Calculate the velocity of climate change over a given set of years

Usage

1
get_vocc(hadsst_raster, years = 1969:2009, truncate = FALSE)

Arguments

hadsst_raster

the HadISST data as a raster object.

years

a numeric vector specifying the years over which the velocity of climate change will be calculated.

truncate

logical expression indicating whether minimum and maximum values should be constrained to -200 < x < 200. Default is TRUE.

Value

a two-layer raster containing 'velocity_mag' and 'velocity_angle', the magnitude and direction of the velocity of climate change, respectively.
