I have 4 types data sets, Daily global maps of Earth’s surface temperature and near-surface air temperature, precipitable water and cloud water path for the whole year 2004. Map covers whole globe at 2.5 degree intervals = 72 x 144 array. How can I make a global map?

If you have the Mapping Toolbox, geoshow with worldmap is usually good for a first pass:
data = rand(72,144);
rv = [0.4 90 0];
geoshow(data, rv, 'displaytype', 'texturemap');
C = load('coast');
plotm(C.lat, C.long, 'k');
Note that here I'm georeferencing using a reference vector, rv, which defines your grid resolution (0.4 cells/degree) and corner (upper left corner at 90N, 0E).
Alternatively, if you want more control over the projection, plotting details, etc., look into axesm, pcolorm, surfm, etc.
