	Climate zones are a useful way of classifying regional climate. They are defined here based on the updated Köppen-Geiger climate classification (Peel et al., 2007), which is available to download in the ~~[http://www.hydrol-earth-syst-sci.net/11/1633/2007/hess-11-1633-2007-supplement.zip~~ supplementary material] to the paper presented by Peel et al. (2007).		Climate zones are a useful way of classifying regional climate. They are defined here based on the updated Köppen-Geiger climate classification (Peel et al., 2007), which is available to download in the supplementary material to the paper presented by Peel et al. (2007).

	The Köppen-Geiger classification is a widely used scheme that has been updated using long-term station records of monthly precipitation and temperature from the Global Historical Climatology Network (GHCN) version 2.0 dataset. Similarly with all derived datasets, the reliability of the dataset is dependent on the density of input data. Detailed information on the classification system can be found in Peel et al. (2007).

	The number of station observations in each grid cell at each monthly time-step have been averaged over the period 1951–2010 and are shown on the maps below. The data from each station can influence the interpolated (gridded) value in a given cell if it lies within a predefined Correlation Decay Distance of another station: set at 450 km for precipitation data and 1200 km for temperature data. For Africa, approximately 75% of the grid cells contain station data, or have station data within the correlation decay distance, with valid values over the period 1901–2000.

	The reliability of the climate data depends on the number of climate monitoring stations providing the data used in interpolation of the gridded dataset. In some areas of Africa, there are few climate monitoring stations and they are spaced far apart; and not all stations have continuous records over time. Only data from stations which have a >75% complete record over the period ~~1961-1990~~ were used in the development of the CRU TS 3.21 dataset.

	The maps below illustrate the density of climate monitoring stations across Africa, and therefore the availability of climate data. They act as a proxy to indicate the reliability of the interpolated climate dataset. In areas where there are fewer stations, the interpolated precipitatation and temperature data should be treated as less reliable than in areas where there is a higher density of stations.
