An intercomparison of two kinds of wire icing observed data in China is performed to analyze the differences in diameter, thickness, weight, standard thickness of the wire ice in this study. The difference in the two icing observations under different weather phenomena and meteorological conditions is also discussed. The results show that the two kinds of wire ice (north south and east west) diameter, thickness and standard thickness data, which were collected by majority of the stations in the country from January to May 2011, have no significant difference. However, the difference in weight between the two datasets is obvious, especially in the areas to the south of the Yangtze River. Further analysis shows that the differences in ice thickness and diameter between the two datasets under the rime and mixed icing conditions are more significant, while the difference in ice weight reaches the maximum when the wind force is from Grade 0 to 3, the temperature ranges between -5℃ and 0℃, and the glaze occurs.
