get_spatial_gradient: Calculate the spatial gradient of temperature change.

In jebyrnes/hadsstR: Calculate the Velocity of Climate Change Using Hadley Centre SST

Description

Calculate the spatial gradient of temperature change.

Usage

get_spatial_gradient(NS_gradient, WE_gradient)

Arguments

NS_gradient	single-layer raster containing the north to south spatial gradient between neighbouring cells
WE_gradient	single-layer raster containing the west to east spatial gradient between neighbouring cells

Value

a two-layer raster containing 'spatial_gradient', the magnitude of the spatial gradient and 'angle', the direction of the spatial gradient.
