This dataset depends on the following independent variable (i.e, grid):
grid: /S (days since 1960-01-01) ordered [ (Jan 1960) (Feb 1960) (Mar 1960) (Apr 1960) (May 1960) (Jun 1960) (Jul 1960) (Aug 1960) (Sep 1960) (Oct 1960) (Nov 1960) (Dec 1960)] :grid
so there will be 12 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://45.183.221.150/SOURCES/.NextGen/.CPT/.Estacional/.CHIRPS/.Guatemala/.V2/.Models/.COLA-RSMAS-CCSM4/.Skill/.2AFC/S/%28days%20since%201960-01-01%29streamgridunitconvert/downloadsarcinfo.html'
single quotes are necessary in unix to protect the url from expansion; probably necessary in other cases as well
