| Popis | In this contribution, we focus on microclimate and active layer measurements at the Johann Gregor Mendel station and Johnson Mesa located on Ulu Peninsula (James Ross Island, northern Antarctic Peninsula). The effect of air temperature and global radiation on ground temperature variation was studied with respect to the site characteristics and snow occurrence in the period of 2011-2013. Mean annual ground temperatures between both sites confirmed the strong dependence on altitude. The correlation analysis showed that the highest influence of the air temperature on the ground temperature was observed in days without snow cover during winter season. Conversely, the significant decrease of the air temperature influence was found in days with snow cover higher than 7 cm and/or in days without snow cover during summer. |
