Daily automated in-situ ground-based meteorological surface observations in the Netherlands

KNMI collects meteorological surface observations from automatic weather stations (in-situ) situated in the Netherlands and BES islands. The network consists of sea and land-based locations, including wind poles and sites at airports. The weather stations report every 10 minutes meteorological variables such as temperature, relative humidity, wind, air pressure, visibility, precipitation and cloud cover. The 10 minute observations are aggregated to daily values once per day.

The number of available variables differs per station. The file for the daily interval is available the next day and contains a timestamp denoting the end of the observation interval in UTC. It is possible that a station's observations may not be immediately available. The dataset can be updated with missing observations up to seven days later.
