SE.ACMF Meteorological observations — Relative humidity hourly

Purpose: Purpose: Describes current weather and over time the climate. Basis for forecasting and climate studies. Unit: % Characteristics: Relative humidity measured at measuring stations. Instantaneous value each and every three hours. Design: Date, time, value and quality. Quality codes: Green = Verified and accepted values. Yellow = Suspected values, aggregated values, roughly controlled archive data and uncontrolled real-time data (last 2 hours). Limits: 0 to 100 % For more info see: https://www.smhi.se/kunskapsbanken/meteorologi/luftfuktighet-1.3910 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 24 hours, the last four months or the full time series except for the last three full months (historical reviewed). 2. Via a machine-machine solution (Atom flow rate). There, the same measurement series as above can be obtained as well as real-time data. These are the last hour’s readings. They can be retrieved for one measuring station at a time or for all active measuring stations.
