SE.OF Oceanographic observations — seawater level RH2000, minute value

Purpose: Analyse trends, land rise and sea level rise. Unit: cm Characteristics: Seawater level in the elevation system RH2000 (Sweden’s new national altitude system). An instantaneous reading per minute. Design: Date, time, value, quality and depth of measurement. Quality codes: Green (G) = Verified and accepted values. Yellow (Y) = Coarsely controlled values, suspicious or aggregated values. Orange (O) = Uncontrolled values Limits: Both >0 and <0. For more info see: station list: https://www.smhi.se/kunskapsbanken/oceanografi/matstationer-for-havsvattenstand-1.13981 For information about the current year’s mean water level or for recalculation between different altitude systems, you can find updated information here: https://www.smhi.se/data/oceanografi/havsvattenstand Delivery: Data is delivered in two different ways 1. Via a user interface where measurement series can be downloaded for one station at a time Data can be downloaded for the last hour, last day or full time series except the last day(historical reviewed) 2. Via a machine-machine solution (Atom flow rate). Where the same series of measurements as above can be obtained and also real-time data. These are the last hour’s readings. They can be retrieved for a measuring station at a time or for all active measuring stations.研究用途：用于分析趋势、陆地抬升与海平面上升情况。 计量单位：厘米（cm） 数据特征：采用瑞典新版国家高程系统RH2000（Sweden’s new national altitude system）记录的海水水位数据，每分钟采集一次瞬时观测值。 数据字段构成：包含测量日期、时间、观测数值、质量等级与测量深度。 质量编码规范：绿色（G）代表经验证并确认接收的有效数值；黄色（Y）代表经过粗略质控、存疑或聚合后的数值；橙色（O）代表未经过质控的数值。 数值范围：支持同时包含大于0与小于0的数值。 更多信息请查阅测站列表：https://www.smhi.se/kunskapsbanken/oceanografi/matstationer-for-havsvattenstand-1.13981 如需获取本年度平均水位信息或不同高程系统间的数值转换方法，可访问以下链接获取最新资料：https://www.smhi.se/data/oceanografi/havsvattenstand 数据交付方式：支持两种交付渠道： 1. 通过用户界面交付：可单次单站下载测量序列数据，支持下载最近1小时、最近1天的观测数据，以及除当日外的完整历史审核时序数据。 2. 通过机器对机器（M2M）方案（Atom 流量传输）交付：可获取与上述渠道一致的测量序列数据，同时还可获取实时数据（即最近1小时的观测读数），支持单次单站或全活跃测站的数据调取。
