I'am trying to find annual mean temperature data for all countries in Africa for past 50 years.

The data should not be mean of the entire 20 years, but should be yearly mean.
Can somebody please redirect me to a good source of data?

This is for research work.

  • This question looks like it would be better researched/asked at Open Data.

  • The World Bank is usually a good source for stuff like this. I don't think you'll get data from 50 years back, though

    It's not a good idea to use 'country' as the spatial entity.

A good source 1961-1999 is http://gaez.fao.org/Main.html#

lots of atmospheric parameters can be found at (1979-2015): http://apps.ecmwf.int/datasets/data/interim-full-daily/

You can use zonal statistics with country polygons to obtain annual values per country. You can get country shapefiles at http://www.naturalearthdata.com/features/
