WeightedCells: Compute the square-root of the cosine of the latitude...

In ClimProjDiags: Set of Tools to Compute Various Climate Indices

Compute the square-root of the cosine of the latitude weighting on the given array.

Description

This function performs square-root of the cosine of the latitude weighting on the given array.

Usage

WeightedCells(data, lat, lat_dim = "lat", method = "cos", ncores = NULL)

Arguments

data	A numeric array with named dimensions, representing the data to be applied the weights. It should have at least the latitude dimension and it can have more other dimensions.
lat	A numeric vector or array with one dimension containing the latitudes (in degrees).
lat_dim	A character string indicating the name of the latitudinal dimension. The default value is 'lat'.
method	A character string indicating the type of weighting applied: 'cos' (cosine of the latitude) or 'sqrtcos' (square-root of the cosine of the latitude). The default value is 'cos'.
ncores	An integer indicating the number of cores to use for parallel computation. The default value is NULL.

Value

An array containing the latitude weighted data with same dimensions as parameter 'data'.

Examples

exp <- array(rnorm(1:30), dim = c(lat = 3, lon = 5, sdate = 2))
lat <- c(10, 15, 20)
res <- WeightedCells(data = exp, lat = lat)
