RCMIP5 (version 1.2.0)

filterDimensions: Filter dimensions, limiting to arbitrary lon/lat/Z/time ranges

Description

We frequently want to filter CMIP5 data according to some predetermined criteria: only high-latitude cells, for example, or certain years, months, Zs, etc. This function provides convenient one-stop service for such tasks.

Usage

filterDimensions(x, lonRange = NULL, latRange = NULL, ZRange = NULL, yearRange = NULL, monthRange = NULL, verbose = FALSE)

Arguments

x

A cmip5data object

lonRange

Longitude values (min, max) to filter data against

latRange

Latitude values (min, max) to filter data against

ZRange

Z values (min, max) to filter data against

yearRange

Years (min, max) to filter data against

monthRange

Months (min, max) to filter data against

verbose

logical. Print info as we go?

Value

The filtered cmip5data object.

Examples

d <- cmip5data(1970:2014)   # sample data
filterDimensions(d, yearRange=c(1980, 1985))
filterDimensions(d, monthRange=c(6, 8))  # summer
filterDimensions(d, latRange=c(-20, 20))  # the tropics
filterDimensions(d, latRange=c(-20, 20), monthRange=c(6, 8))  # tropical summer
