Daily values of weather observations: Rovaniemi Misi

The data includes computational and measured daily values from the Finnish Meteorological Institute's weather observation station. The calculated values are the daily average air temperature and the daily precipitation. Measured values include minimum and maximum air temperature, minimum ground temperature and snow depth. The extremes of air temperature are measured at 06 and 18 UTC and the minimum ground temperature at 06 UTC. These represent extreme values over the previous 12-hour period (18-06 and 06-18 UTC).本数据集包含芬兰气象研究所（Finnish Meteorological Institute）气象观测站的计算日值与实测日值数据。其中计算值包括日平均气温与日降水量；实测值则涵盖日最低气温、日最高气温、最低地面气温及积雪深度。气温极端值的观测时刻为世界协调时（UTC）06时与18时，地面最低气温则于UTC 06时开展测量，上述极端值分别对应此前12小时的观测时段：即UTC 18时至次日06时，以及UTC 06时至18时。
