Daily values of weather observations: Nurmijärvi Rajamäki

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）气象观测站的计算与实测日值数据。其中计算值为日平均气温与日降水量；实测值涵盖日最低气温、日最高气温、地表最低温度以及积雪深度。气温极值的观测时间为协调世界时（UTC）的06时与18时，地表最低温度的观测时间为协调世界时06时。上述极值对应此前12小时观测时段（即协调世界时18时至06时，以及06时至18时）的观测结果。
