This paper presents the applications of Kriging spatial interpolation methods for meteorologic variables,including temperature and relative humidity, in regions of Vietnam. Three types of interpolation methods areused, which are as follows: Ordinary Kriging, Universal Kriging, and Universal Kriging plus Digital Elevationmodel correction. The input meteorologic data was collected from 98 ground weather stations throughoutVietnam and the outputs were interpolated temperature and relative humidity gridded fields, along with theirerror maps. The experimental results showed that Universal Kriging plus the digital elevation modelcorrection method outperformed the two other methods when applied to temperature. The interpolationeffectiveness of Ordinary Kriging and Universal Kriging were almost the same when applied to bothtemperature and relative humidity.
