This dataset depends on the following independent variable (i.e, grid):
grid: /T (days since 1960-01-01) periodic [ (0000 2 Jan) (0000 12 Jan) (0000 21 Jan) (0000 2 Feb) (0000 12 Feb) (0000 21 Feb) (0000 1 Mar) (0000 11 Mar) (0000 20 Mar) (0000 1 Apr) (0000 11 Apr) (0000 20 Apr) (0000 1 May) (0000 11 May) (0000 20 May) (0000 1 Jun) (0000 11 Jun) (0000 20 Jun) (0000 1 Jul) (0000 11 Jul) (0000 20 Jul) (0000 1 Aug) (0000 11 Aug) (0000 20 Aug) (0000 1 Sep) (0000 11 Sep) (0000 20 Sep) (0000 1 Oct) (0000 11 Oct) (0000 20 Oct) (0000 1 Nov) (0000 11 Nov) (0000 20 Nov) (0000 1 Dec) (0000 11 Dec) (0000 20 Dec)] :grid
so there will be 36 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://maproom.metmalawi.gov.mw:8091/SOURCES/.Malawi/.dekadal/.rainfall/rfe_mergeddiff_percent/T+integral/yearly-climatology/COARDS/T/%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
