| Zusammenfassung |
| Weather radar data volumes are commonly processed to obtain various 2-D
Cartesian products based on the transfer from polar to Cartesian
representations through a certain interpolation method. In this research an
algorithm of the spatial interpolation of polar reflectivity data employing
quality index data is applied to find the Cartesian reflectivity as plan position indicator products. On this basis, quality-based versions of
standard algorithms for the generation of the following products have been
developed: ETOP (echo top), MAX (maximum of reflectivity), and VIL
(vertically integrated liquid water). Moreover, as an example of a
higher-level product, a CONVECTION (detection of convection) has been
defined as a specific combination of the above-listed standard products. A
corresponding quality field is determined for each generated product, taking
into account the quality of the pixels from which a given product was
determined and how large a fraction of the investigated heights was scanned.
Examples of such quality-based products are presented in the paper. |
