This dataset depends on the following independent variable (i.e, grid):
grid: /T (days since 1960-01-01) ordered [ (1-10 Jan 2019) (11-20 Jan 2019) (21-31 Jan 2019) (1-10 Feb 2019) (11-20 Feb 2019) (21-28 Feb 2019) (1-10 Mar 2019) (11-20 Mar 2019) (21-31 Mar 2019) (1-10 Apr 2019) (11-20 Apr 2019) (21-30 Apr 2019) (1-10 May 2019) (11-20 May 2019) (21-31 May 2019) (1-10 Jun 2019) (11-20 Jun 2019) (21-30 Jun 2019) (1-10 Jul 2019) (11-20 Jul 2019) (21-31 Jul 2019) (1-10 Aug 2019) (11-20 Aug 2019) (21-31 Aug 2019)] :grid
so there will be 24 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://213.154.77.59/SOURCES/.Estation/.vgt-dmp/.v2p0/.SPOTV-ECOWAS/dmp/downloadsarcinfo.html'
single quotes are necessary in unix to protect the url from expansion; probably necessary in other cases as well
