Description

anom.prec provides a method to estimate the anomoly as a proportionate estimate of the future or past climate relative to the current.

Usage

anom.prec(nc1, nc2)

Arguments

nc1

a list object as created by retrieve.nc, extract.monthly.average or append.nc. The minimum set of elements in the list must be dat, lat, lon and tim. See value for a description of these elements.

nc2

a list object as described in nc1.

Value

returns an object that is a list with the same elements as nc1 with the dat element being the anomoly as a proportion of current.

the list will contain at least:

dat

an array containing the anomoly data. The dimensions of the array represent:
1 - time described in this list by tim
2 - latitude (or y element) described in this list by lat
3 - longitude (or x element) described in this list by lon

lat

vector of latitudes

lon

vector of longitudes

tim
