comment
This dataset is described in Chaney and Sheffield (2012) (Chaney, N., and J. Sheffield, 2012: High Resolution Gridded Daily Meteorological Data for Africa: Dataset Development and Analysis of Trends in Means and Extremes, J. Climate, to be submitted) and is related to the original global version reported in Sheffield et al., J. Climate (2006). Updates/changes include: i. 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. See Sheffield et al., J. Climate (2006) for details of the observations used and the bias correction and downscaling methodology.
