satin-class {satin}

Class "satin"

Description

class for ocean data derived from satellites, imported from netCDF files.

Objects from the Class

Objects of class "satin" are created by importing functions: read.nasaoc, read.ghrsst, read.cmems, and read.osunpp. They can also be created, though not recommended, by direct calls to satin.

Slots

lon

Object of class "numeric"; vector of longitudes of the area of interest (aoi).

lat

Object of class "numeric"; vector of latitudes of the aoi.

data

Object of class "array"; three or four dimensions array of ocean data corresponding to the lengths of lat, lon, period$tmStart, and depth vectors. The fourth dimension associated to depth levels will only be present in "satin" objects derived from Copernicus data files.

attribs

Object of class "list"; attributes of the data stored in the netCDF file: title: title attribute from netCDF file; longname: long name of ocean data variable; name: short name of ocean data variable; units: ocean data variable measurement units; temporal_range: averaging period length, i.e. daily, monthly, etc.; spatial_resolution: spatial resolution of the ocean data variable.

period

Object of class "list"; a vector with start time (tmStart) and a vector with end time (tmEnd) of the averaging period of the data. Both vectors are of class "POSIXct".

depth

Object of class "numeric"; vector of depth levels in the data. Only meaningful for "satin" objects derived from Copernicus data files.

Methods

plot

signature(x = "satin", y = "missing"): plot method for "satin" objects. See details in plot.satin

show

signature(object = "satin"): display a summary of the object. See example below
