By using the micrometeorological observation data in a mossy area and the daily meteorological data of Great Wall Station (GWS) in the Antarctic, two microclimate features are revealed in this study. First, the amplitude of diurnal variation of temperature in the lower layer above the ground in the mossy area is decreasing rapidly with altitude under any kind of weather conditions; Second, the difference between the diurnal mean surface (0 cm height) temperature and mean surface air (150cm height) temperature in the mossy area is much smaller than in GWS. The aforesaid difference is probably due to the difference between the moss cushion in the microclimatic observation field and the bare sandy soil in GWS, that may have an important influence on the microclimate features of those areas.
