Thanks for your comments.

This one does not cover the period, you are interested in, but provides some general information on various products: http://dx.doi.org/10.1002/joc.4346 (Uncertainties in remotely sensed precipitation data over Africa).

Here is one we did in 2006 and another more recent paper using CRU. I think there are others aswell, but I will have to look a bit deeper.
