Daily values of weather observations: Credit Eugmo

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）所属气象观测站的计算型与实测型日度气象数据。其中计算型数据为日平均气温与日降水量；实测型数据涵盖最低气温、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协调世界时（UTC）06时与18时，最低地面气温的观测时刻为协调世界时06时，上述观测值分别对应此前12小时时段（协调世界时18时至06时、06时至18时）的极端气象指标。
