I'm looking for annual (or monthly) rainfall data over time and by country (specifically, for sub-Saharan African countries). I've been able to find data up to the year 2000. I know there has got to be more recent data but I'm having trouble finding it! Any suggestions would be much appreciated.

The European Centre for Medium Range Weather Forecasts hosts a database with this information here: http://apps.ecmwf.int/datasets/data/interim-full-daily/levtype=sfc/

They require you to create an account (free) before you can request data. The data is available per lat/lon grid point, so you'll have to look up which grid points are within which country.

As for the data, you'll probably want the Total precipitation field (this also includes hail and snow, but that won't be much in the sub-Sahara).
