Gaussianize field using rank ordering
The amplitudes of the input field are rank ordered and substituted with the corresponding rank-ordered samples from a Normal distribution.
gaussianize(z)
z |
matrix containing the input field to be Gaussianized. |
The Gaussianized field with the same dimensions as the input field.

# Make some sample synthetic rainfall data r <- exp(rnorm(64 * 64)) dim(r) <- c(64, 64) # Gaussianize and check standard deviation g <- gaussianize(r) sd(g) # [1] 1
