Documentatie Actuele10mindataKNMIstations

Het KNMI verzamelt waarnemingen van de automatische weerstations die in Nederland en op de BES-eilanden staan op locaties als vliegvelden en Noordzeeplatforms. Daarnaast worden windgegevens van de KNMI-windmasten meegenomen. De weerstations rapporteren elke 10 minuten meteorologische parameters zoals temperatuur, relatieve vochtigheid, wind, luchtdruk, zicht, neerslag en bewolking. Het aantal parameters verschilt per station. Het bestand over de afgelopen 10-minuten is enkele minuten later beschikbaar. Het kan voorkomen dat de waarnemingen van een station niet direct beschikbaar zijn. Bestanden worden tot 4 uur later nog bijgewerkt met ontbrekende waarnemingen.

Stopzetten dataset

Deze dataset wordt stopgezet en zal vanaf 29-09-2025 geen updates meer ontvangen. U wordt geadviseerd de nieuwe dataset 10-minute-in-situ-meteorological-observations te gebruiken of over te stappen naar de nieuwe bijbehorende EDR API-collectie. Meer informatie over het stopzetten van deze dataset kunt u hier vinden. Voor meer informatie over de dataset, zie de documentatie van deze dataset.

Doel

Deze actuele 10 minuten dataset is bedoeld als near real-time dataset, zodat de waarnemingen zo snel mogelijk beschikbaar zijn. Andere datasets hebben als doel zo compleet mogelijk te zijn, zoals de data van daggegevens.knmi.nl. Sommige stations hebben meerdere sensoren van hetzelfde type, wat betekent dat verschillende sensoren verantwoordelijk kunnen zijn voor dezelfde variabelen. In de regel kunnen beide meetreeksen als representatief worden beschouwd en zijn ze gekalibreerd en onderhouden. Alle sensoren zijn gevalideerd voor klimatologische doeleinden.

Als je meer wilt weten over welke stations worden gebruikt in deze dataset en waar ze zich bevinden, ga dan naar de waarneemstations dataset op het dataplatform. Alle beschikbare stations die gegevens leveren zijn nu toegevoegd. Windmasten en stations in de Noordzee zijn bijvoorbeeld opgenomen in de Actuele10mindataKNMIstations. Het is echter belangrijk op te merken dat sommige van deze meetstations mogelijk nog niet volledig operationeel zijn. De observaties blijven representatief en geldig voor de gemeten weersomstandigheden, maar zijn nog niet opgenomen in de klimatologisch gevalideerde datasets.

Opmerking: Niet alle variabelen worden op alle stations gemeten.

Alle variabelen, die mogelijk worden gemeten bij een of meerdere stations, hebben we samengevat in de onderstaande lijst. Het kan zijn dat er een opmerking bij de variabelen is, deze is in de tabel eronder uitgeschreven.

MD = Marked Discontinuity. Een sterke wijziging in windsnelheid en/of -richting (10 knopen, 30 graden, minimaal 2 minuten) binnen een 10-minuten interval. Na een MD worden de waarden voor het MD niet meer meegenomen in het berekenen van het 10-minuten gemiddelde. Naar richtlijnen van WMO en ICAO.
