#' NASA spatio-temporal data
#'
#' This data comes from the ASA 2007 data expo,
#' \url{http://stat-computing.org/dataexpo/2006/}. The data are geographic and
#' atmospheric measures on a very coarse 24 by 24 grid covering Central
#' America. The variables are: temperature (surface and air), ozone,
#' air pressure, and cloud cover (low, mid, and high). All variables are
#' monthly averages, with observations for Jan 1995 to Dec 2000. These data
#' were obtained from the NASA Langley Research Center Atmospheric Sciences
#' Data Center (with permission; see important copyright terms below).
