        <gco:CharacterString>Gridded files of radar-derived 5 minute precipitation accumulations, corrected by rain gauge data. Radar data over the Netherlands and surrounding area measured by Dutch, Belgian, and German radars are corrected by available data from automatic and manual rain gauges. Time interval is 5 minutes.
  
Starting with data from 31 January 2023 - 10.45 UTC onwards, this dataset is created using improved algorithms. This includes correction for signal attenuation, correction for vertical variation of precipitation, correction for fast-moving showers and use of uncertainty information in merging data from multiple radars.
 
Starting with data from 18 November 2024 - 14.40 UTC onwards, this dataset is created using improved methodologies. This includes a) the usage of additional rain gauge data from water authorities and water companies, b) a two-step methodology to construct based on rain gauge data a large-scale and localised adjustment field for correcting precipitation estimates; and c) reducing the quality indication of data of the Herwijnen radar of the lowest two elevations and for a small set of azimuth angles, to mitigate beam blockage due to trees and wind turbines.</gco:CharacterString>

Radargegevens gemeten door Nederlandse, Belgische en Duitse radars boven Nederland en omstreken worden gecorrigeerd met de beschikbare regenmetergegevens uit automatiche en handmatige weerstations. Het tijdsinterval is 5 minuten. 
  
Startend vanaf 31 januari 2023 - 10.45 UTC, is de data van deze dataset gemaakt met behulp van verbeterde algoritmen. Dit omvat correctie voor signaalverzwakking door neerslag, correctie voor verticale variatie van neerslag, correctie voor snel bewegende buien en gebruik van onzekerheidsinformatie bij het samenvoegen van gegevens van meerdere radars.
 
Startend vanaf 18 november 2024 - 14.40 UTC, is de data van deze dataset gemaakt met behulp van verbeterde methoden. Dit omvat a) het gebruik van aanvullende regenmetergegevens van waterschappen en waterbedrijven, b) een tweestapsmethode om op basis van regenmetergegevens een grootschalig en lokaal aanpassingsveld te construeren voor het corrigeren van neerslagschattingen; en c) het verminderen van de kwaliteitsindicatie van gegevens van de Herwijnenradar voor de laagste twee elevaties en voor een kleine set azimuthoeken, om het effect van bundelblokkering door bomen en windturbines te verminderen.</gmd:LocalisedCharacterString>

            <gco:CharacterString>Radar reflectivities are measured by radars in the Netherlands, Belgium, and Germany. Single images per radar at 1500 m height are generated by linearly interpolating radar reflectivities in altitude.

A mean bias correction factor is derived based on the most recent 1 hour rainfall accumulations from automatic rain gauges. The resulting radar rainfall estimates from all radars are then combined to a single product by taking a weighted average. The weigths are a function of the distance of a given point to the radar.

Per radar wordt een beeld gemaakt dat zo dicht mogelijk bij 1500 m hoogte ligt door radarreflectiviteiten lineair te interpoleren in de hoogte. De radarreflectiviteiten worden vervolgens geconverteerd naar neerslagintensiteiten door de relatie Z=200R^1.6 te gebruiken. Een correctiefactor wordt berekend op basis van de meest recente 1 uur accumulatie van automatische regenmetergegevens. De resulterende radar neerslagschattingen worden vervolgens gecombineerd door een gewogen gemiddelde te nemen. De gewichten zijn afhankelijk van de afstand van een punt tot de radar.
