levitus: Annually-averaged sea-surface temperature and salinity

Description

Sea-surface temperature and salinity from the 2013 version of the World Ocean Atlas (WOA), commonly referred to as the Levitus atlas, in the form of a list containing longitude, latitude, and sea-surface salinity SSS and temperature SST. See References 2 and 3 for more information about the dataset.

Usage

data(levitus, package="ocedata")

Details

The levitus dataset was constructed from the World Ocean Atlas as of 2013, downloaded from Reference 1. The data were read with ncdf4, and the top layers of temperature and salinity were selected. Then longitude was shifted from (0,360) notation to the (-180,180) notation used by oce.
