Read a World Ocean Atlas NetCDF File

Description

Read a World Ocean Atlas NetCDF File

Usage

read.woa(file, name, positive = FALSE, encoding = NA)

Arguments

`file`	character string naming the file
`name`	of variable to extract. If not provided, an error message is issued that lists the names of data in the file.
`positive`	logical value indicating whether `longitude` should be converted to be in the range from 0 to 360, with `name` being shuffled accordingly. This is set to `FALSE` by default, because the usual oce convention is for longitude to range between -180 to +180.
`encoding`	ignored.

Value

A list containing vectors longitude, latitude, depth, and an array with the specified name. If positive is true, then longitude will be converted to range from 0 to 360, and the array will be shuffled accordingly.

Sample of Usage

# Mean SST at 5-degree spatial resolution
tmn <- read.woa("~/data/woa13/woa13_decav_t00_5dv2.nc", "t_mn")
imagep(tmn$longitude, tmn$latitude, tmn$t_mn[, , 1], zlab="SST")
