SE.ACMF Hydrological Observations — Water, Quartz Value

Purpose: Describe Sweden’s hydrology. Used for forecasts and warnings, climate studies and scenarios for infrastructure, nutrient transport and flood mapping, etc. Unit: m³/s Features: Describes the amount of water per unit of time that flows into a stream. Data for the last hour and day are delivered as 4 quartz values/hour. Historical data are delivered as daily values where the days are in Swedish summer time, which means that the Swedish day starts at 22 UTC the day before. The time stamp indicates the start time of the time step in UTC. Quality Codes: Green (G) = Verified and approved values. Yellow (Y) = Coarse controlled values, suspicious or aggregated values. Orange (O) = Uncontrolled values Boundaries: >=0用途：本数据集用于描述瑞典水文状况，可支撑水文预报与预警、基础设施相关气候研究与情景分析、营养盐输运模拟以及洪水制图等多项工作。 单位：立方米每秒（m³/s） 特征：该数据集表征单位时间内流入河道的水量。近1小时与近1日的观测数据以每小时4组的频次发布。历史数据为日度统计值，采用瑞典夏令时计时规则，即瑞典的一日起始于前一日的协调世界时（UTC）22时。数据时间戳以协调世界时（UTC）标注对应时段的起始时刻。 质量编码规则：绿色（G）代表经核实并批准的有效数据；黄色（Y）代表经粗略质控、存疑或聚合生成的数据；橙色（O）代表未开展质控的数据。 数值范围：≥0
