destdir, then it is not
downloaded again. The default destdir is the present directory,
but it probably makes more sense to use something like "~/data/amsr"
to make it easy for scripts in other directories to use the cached data.
download.amsr(year, month, day, destdir = ".", server = "ftp.ssmi.com/amsr2/bmaps_v07.2")day and month are not provided but day is,
then the time is provided in a relative sense, based on the present
date, with day indicating the number of days in the past.
Owing to issues with timezones and the time when the data
are uploaded to the server, day=3 may yield the
most recent available data. For this reason, there is a
third option, which is to leave day unspecified, which
works as though day=3 had been given.download.* functions are subject to change through the
autumn of 2016. The plan is to create individual functions
as needs arise in everyday work, thereby discovering patterns of
arguments that might make sense more generally. Therefore, it is likely
that argument order (and even name) may change up until approximately
December 2016. Users are advised to refer to arguments by name,
i.e. not to rely on their order, and they are asked for patience,
because argument names and defaults may vary through the early development.ftp, and also on local directories
being separated by forward slashes in the file system. That means it will probably
only work on unix-like systems.
