Inspiration Controlled climatic day data

The KNMI manages 33 automatic weather stations on land. These weather stations measure meteorological parameters such as temperature, precipitation, wind, air pressure and global radiation. All hourly observations and measurements received in real time are checked daily for accuracy and completeness. The validated data are archived in the Klimatological Information System (KIS) of the KNMI. Daily data are compiled from the hourly data and once a day the reference crop evaporation is calculated using the Makkink method. After processing and archiving the data in KIS, it can no longer be changed. This ensures data integrity.荷兰皇家气象研究所（KNMI）在陆域范围内布设了33座自动气象站。这些气象站可监测气温、降水、风速、气压及总辐射等各类气象参数。所有实时接收的逐小时观测与测量数据，每日都会开展准确性与完整性校验。经校验合格的数据将归档至KNMI的气候信息系统（Klimatological Information System，简称KIS）。研究人员基于逐小时数据合成日尺度数据集，并每日通过Makkink法计算参考作物蒸散量。数据在KIS中完成处理与归档后将无法进行任何修改，此举可有效保障数据完整性。
