Vertical reflectivity profile

Description


Radar product giving the vertical profile of the reflectivity taken over a specified surface area. For each height level this product delivers a set of parameters that describes the reflectivity field inside the considered volume. The Vertical profile of reflectivity is the main factor in the accurancy of precipitation measurements at distances of 50-250 km. The origins of large bias of 2-20 dB are based on the difference between the actual reflectivity of ground level and in the contribution volume aloft.

Notes

• The profile is taken in a vertical cylinder based above a ground area of specified form and position. Typically it is taken within a circular area centred around the radar station. If this is not the case (e.g. for an arbitrary form) the surface is described by its gravity centre and equivalent radius.
• The data quantification method describes the algorithm used to associate a reflectivity value to an height level. "When the vertical stratification is not regular the sequence of the used heights is to be specified.
• The base area and the quantification method can optionally be omitted.
