This dataset depends on the following independent variable (i.e, grid):
grid: /S (days since 1960-01-01) periodic [ (0000 1 Jan 1960) (0000 1 Feb 1960) (0000 1 Mar 1960) (0000 1 Apr 1960) (0000 1 May 1960) (0000 1 Jun 1960) (0000 1 Jul 1960) (0000 1 Aug 1960) (0000 1 Sep 1960) (0000 1 Oct 1960) (0000 1 Nov 1960) (0000 1 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://kmddl.meteo.go.ke:8081/SOURCES/.KMD/.Forecast/.CPT/.Rainfall/.Seasonal/.History/.PearsonR/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
