get.sst: Read SST data from online service.

In tripEstimation: Metropolis sampler and supporting functions for estimating animal movement from archival tags and satellite fixes

Description

Functions to read SST data from online services, by specifying spatial and temporal bounds.

Usage

get.sst(xlim = NULL, ylim = NULL, tlim = NULL, server = "http://atlas.nmfs.hawaii.edu/cgi-bin/reynolds_extract.py")

Arguments

xlim	Longitude range of SST to read.
ylim	Latitude range of SST to read.
tlim	Time range of SST to read.
server	Server to read from.

Details

This functionality was originally taken from the kfsst package by Anders Nielsen.

Longitude xlim range may be specified in [-180, 180] or [0, 360] convention. The result is given in [-180, 180].

Time range must be given in POSIxct form.

Value

A list object with the temperature data and coordinates.

x,y,t	Coordinates of the temperature data
z	Matrix or array of temperature data
