These scans are used to generate a single image per radar at 1500 m by linearly interpolating radar reflectivities in altitude. These two radar images are then combined to a single image by taking a weighted average of the radar reflectivities. The weigths are a function of the distance of a given point to the radar.

Van deze scans wordt per radar een beeld gemaakt dat zo dicht mogelijk bij 1500 m hoogte ligt door radarreflectiviteiten lineair te interpoleren in de hoogte. De twee radarbeelden worden vervolgens gecombineerd door een gewogen gemiddelde van de twee radarreflectiviteiten te nemen. De gewichten zijn afhankelijk van de afstand van een punt tot de radar. De het tijdstip in de bestandsnaam is het tijdstip van het begin van de onderste scan.
