upscaleGrid: Horizontal grid upscaling

In SantanderMetGroup/transformeR: A climate4R package for general climate data manipulation and transformation

Horizontal grid upscaling

Description

Aggregates a grid along the target dimensions using user-defined functions.

Usage

upscaleGrid(grid, times = 5, aggr.fun = list(FUN = max, na.rm = TRUE))

Arguments

grid	a grid or multigrid to be aggregated.
times	Degradation times. For instance, if the resolution of grid is 1 degree and times = 2, the resolution of the output grid will be 2 degrees.
aggr.fun	Upscale function. Default retains the maximum value.

Details

The development of a more eficient and fast version of the function is planned.

Value

A grid or multigrid aggregated along the chosen dimension(s).

                       times = 2,
                       aggr.fun = list(FUN = "min", na.rm = TRUE))
