Air temperature at the summit of Mont Jacques-Cartier (Gaspé peninsula) 2012-2015

The available dataset is the unique continuous measurement of the air temperature on the summit of Mont Jacques-Cartier (1263 m a.s.l.). This summit represents the highest peak of the Chic-Chocs Mountains in the Gaspé Peninsula. This unique site is characterised by typical periglacial landforms (e.g. sorted polygons, sorted stripes, blockfield), by a marginal alpine permafrost body and by a alpine tundra vegetation cover (Gray et al., 2017). Air temperature data are recorded every hour by a U22-001 datalogger (Hobo®; resolution of 0.2°C, accuracy of +/- 0.21°C), which is installed 1 m above the ground surface (GPS: 48°59,268 N; 65°56,937 W). The dataset covers the period 1/12/2012-23/09/2015. The data will be updated after each field trip.

本可用数据集为雅克-卡尔捷山（Mont Jacques-Cartier）峰顶（海拔1263米）的连续气温实测序列，为该站点独有。该峰顶为加斯佩半岛（Gaspé Peninsula）希肖克山脉（Chic-Chocs Mountains）的最高峰。该独特站点发育典型冰缘地貌（periglacial landforms），包括分选多边形、分选条带与石海（blockfield），同时存在边缘性高山多年冻土层与高山苔原植被覆盖（Gray等，2017）。气温数据由安装于地表以上1米处的U22-001型数据采集器（datalogger，Hobo®；分辨率0.2℃，精度±0.21℃）以每小时1次的频率采集，该设备的GPS坐标为48°59.268′ N，65°56.937′ W。本数据集的时间覆盖范围为2012年12月1日至2015年9月23日，后续将随每次野外考察行程更新数据。
