African continent domain; ii. extension to 2005; iii. assimilation of available GHCN/GSOD daily station observations; iv. step change detection and correction for observational datasets; v. improved sampling procedure for correction of rain day statistics; vi. use of latest versions of CRU, SRB and TRMM products; vii. improved consistency between specific and relative humidity and air temperature.
