Daily values of weather observations: Rovaniemi railway station

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).本数据集涵盖芬兰气象研究所（Finnish Meteorological Institute）气象观测站的计算气象日值与实测气象日值。其中计算值包含日平均气温与日降水量；实测值则包括最低气温、最高气温、地面最低温度与积雪深度。气温极值的观测时间为世界协调时（UTC）每日06时与18时，地面最低温度则于每日06时观测，上述观测值分别代表此前12小时周期（世界协调时18时至次日06时、06时至18时）内的极端气象指标。
