VnGP is a daily gridded data set made from the data of 481 rain gauges in Vietnam. The “Spheremap”of Willmott et al. (1985) interpolation method was used. The Spheremap method is originally the weighted two-dimensional spatial interpolation algorithm proposed by Shepard (1968), but modified to work with the spherical coordinates. We have not taken into account of topographical effects, nor the systematic errors of the rain gauges' data.
