Daily temperature data from the Foothills Climate Array Mesonet, Canadian Rocky Mountains, 2005-2010

Near-surface air temperatures were monitored from 2005 to 2010 in a mesoscale network of 230 sites in the foothills of the Rocky Mountains in southwestern Alberta, Canada. The monitoring network covers a range of elevations from 890 to 2880 m above sea level and an area of about 18 000 km², sampling a variety of topographic settings and surface environments with an average spatial density of one station per 78 km². This paper presents the multiyear temperature dataset from this study, with minimum, maximum, and mean daily temperature data. In this paper, we describe the quality control and processing methods used to clean and filter the data and assess its accuracy. Overall data coverage for the study period is 91 %. We introduce a weather-system-dependent gap-filling technique to estimate the missing 9 % of data. Monthly and seasonal distributions of minimum, maximum, and mean daily temperature lapse rates are shown for the region.2005年至2010年，加拿大阿尔伯塔省西南部落基山脉山麓地带搭建了包含230个监测站点的中尺度观测网络（mesoscale network），对近地表气温开展连续监测。该监测网络覆盖海拔范围为890米至2880米，总面积约18000平方千米，采样覆盖多样的地形地貌与地表环境，平均空间布设密度为每78平方千米1个监测站点。本研究公开了本次观测所得的多年气温数据集，包含逐日最低气温、最高气温与平均气温数据。本文详细阐述了用于数据清洗与筛选的质量控制及预处理方法，并对数据集的准确性进行了评估。研究周期内整体数据覆盖率为91%，本研究提出一种依赖天气系统的缺测数据插补技术，用于估算剩余9%的缺失数据。本文展示了该区域逐月与逐季的逐日最低、最高及平均气温递减率（temperature lapse rates）分布特征。
