These data are derived from the 10-minute automatic measurements since the early 1990s, hourly observations from 1951 and daily observations from 1901. The earliest data starts in 1901 with one station and gradually increases to the current measurement network of more than 50 automatic weather stations. The weather stations measure essential climate variables (ECVs), surface precipitation, pressure, global radiation, temperature, water vapor, wind speed and direction, clouds, and visibility. Sunshine duration and potential evapotranspiration are calculated from the ECVs. When applicable, minima, maxima, means, and sums are defined or calculated. This dataset contains meteorological observations since 2015-01-02 at an hourly interval. This dataset contains both observations from the Netherlands as well as the Caribbean Netherlands (BES islands).

Deze waarnemingen zijn geaggregeerd tot uurlijkse, dagelijkse, maandelijkse en jaarlijkse datasets. De gegevens zijn gebaseerd op automatische 10-minutenmetingen sinds begin jaren negentig, uurlijkse waarnemingen vanaf 1951 en dagelijkse waarnemingen vanaf 1901. De oudste gegevens dateren uit 1901, toen metingen begonnen met één station. Inmiddels bestaat het meetnet uit meer dan 50 automatische weerstations. De weerstations meten essentiële klimaatvariabelen, waaronder neerslag, luchtdruk, globale straling, temperatuur, waterdamp, windsnelheid en -richting, bewolking en zicht. Zonneschijnduur en potentiële evapotranspiratie worden berekend uit de klimaatvariabelen. Waar relevant worden minima, maxima, gemiddelden en sommen vastgesteld of berekend. Deze dataset bevat meteorologische waarnemingen vanaf 2015-01-02 op een uurlijkse interval. De gegevens betreffen zowel Nederland als Caribisch Nederland (BES-eilanden).
