<p>This data set contains a collection of GPS coordinates
	   obtained between June 2008 and July 2009.  The GPS tag,
	   developed by the University of Amsterdam, was worn by
	   a lesser black-backed gull (Larus fuscus).</p>

datasets

Contains functions to retrieve, organize, and visualize weather data from the NCEP/NCAR Reanalysis (<http://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis.html>) and NCEP/DOE Reanalysis II (<http://www.esrl.noaa.gov/psd/data/gridded/data.ncep.reanalysis2.html>) datasets.  Data are queried via the Internet and may be obtained for a specified spatial and temporal extent or interpolated to a point in space and time.  We also provide functions to visualize these weather data on a map.  There are also functions to simulate flight trajectories according to specified behavior using either NCEP wind data or data specified by the user.
