This dataset depends on the following independent variable (i.e, grid):
grid: /time (days since 1871-01-01 00:00:00) ordered (0000 1 Jan 1871) to (1800 31 Dec 2008) by 0.25 N= 201616 pts :grid
so there will be 201616 links below for the different files.
You may want to get a utility like wget which can download sets of files. For example (all one line)
wget -r -l2 -nd --no-parent -e robots=off -v --relative 'http://iridl.ldeo.columbia.edu/SOURCES/.NOAA/.ESRL/.PSD/.rean20thcent/.V2/.six-hourly/.monolevel_sprd/.sig995/pottmp/downloadsarcinfo.html'
