Updates include: i) extension to 2006; ii) improved sampling procedure for correction of rain day statistics; iii) use of latest versions of CRU, SRB and TRMM products; iv) 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.";
