This dataset depends on the following independent variable (i.e, grid):
grid: /T (days since 1960-01-01) ordered [ (1200 16 Dec 1959 - 1200 16 Jan 1960) (1200 16 Jan 1960 - 1200 15 Feb 1960) (1200 15 Feb 1960 - 1200 16 Mar 1960) (1200 16 Mar 1960 - 2400 15 Apr 1960) (0000 16 Apr 1960 - 1200 16 May 1960) (1200 16 May 1960 - 2400 15 Jun 1960) (0000 16 Jun 1960 - 1200 16 Jul 1960) (1200 16 Jul 1960 - 1200 16 Aug 1960) (1200 16 Aug 1960 - 2400 15 Sep 1960) (0000 16 Sep 1960 - 1200 16 Oct 1960) (1200 16 Oct 1960 - 2400 15 Nov 1960) (0000 16 Nov 1960 - 1200 16 Dec 1960) (1200 16 Dec 1960 - 1200 16 Jan 1961)] :grid
so there will be 13 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://181.199.253.14/SOURCES/.Hydromet/.CIPH/.CSMT/.RHCondProb/T/%28days%20since%201960-01-01%29streamgridunitconvert/T+integral/X+integral/X+differences/downloadsarcinfo.html'
single quotes are necessary in unix to protect the url from expansion; probably necessary in other cases as well
