Daily values of weather observations: Rauma lighthouse

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).本数据集收录芬兰气象研究所（Finnish Meteorological Institute）气象观测站的计算日值与实测日值数据。其中计算日值为日平均气温与日降水量；实测日值则涵盖日最低气温、日最高气温、地表最低温度及积雪深度。气温极端值于协调世界时（UTC）06时与18时进行观测，地表最低温度则于协调世界时06时观测，上述观测值分别对应前12小时（协调世界时18时至次日06时、06时至18时）内的极端气象数据。
