##' SILO weather data extracted for two arbitrary sites
##'
##' A dataset containing daily weather data in APSIM format for
##' Site_1: at -27 S, 151 E and Site_2: -28 S, 152 E for the period 1
##' to 5 Nov 2020
##'
##' The data were obtained with
##' 
##' \code{two_sites  <- get_multi_silodata(latitude = c(-27.00, -28.00),
##'    longitude = c(151.00, 152.00), Sitename = c("Site_1", "Site_2"),
##'    START = "20201101", FINISH = "20201105", email = "MY_EMAIL_ADDRESS")}
##' 
##' where \dQuote{MY_EMAIL_ADDRESS} was relaced with an appropriate
##' address.
##' 
##' @format A data frame with 10 rows and 11 variables:
##' \describe{
##'  \item{year}{Year}
##'  \item{day}{Day}
##'  \item{radn}{Radiation (MJ/m^2)}
##'  \item{maxt}{Max Temperature (degrees C)}
##'  \item{mint}{Min Temperature (degrees C)}
##'  \item{rain}{Rainfall (mm)}
##'  \item{evap}{Evaporation (mm)}
##'  \item{vp}{Vapour Pressure (hPa)}
##'  \item{code}{Source Code is a six digit string describing the
##'    source of the meteorological data where each digit is either 0, an
##'    actual observation; 1, an actual observation from a composite
##'    station; 2, a value interpolated from daily observations; 3, a
##'    value interpolated from daily observations using the anomaly
##'    interpolation method for CLIMARC data; 6, a synthetic pan
##'    value; or 7, an interpolated long term average}
##'  \item{date_met}{The date on which daily weather was collected}
##'  \item{Sitename}{Sites labelled \dQuote{Site_1} and \dQuote{Site_2}}
##' }
