| Zusammenfassung |
A three-dimensional radar simulator model (RSM) developed by Haase (1998) is
coupled with the nonhydrostatic mesoscale weather forecast model
Lokal-Modell (LM). The radar simulator is able to model reflectivity
measurements by using the following meteorological fields, generated by
Lokal Modell, as inputs: temperature, pressure, water vapour content, cloud
water content, cloud ice content, rain sedimentation flux and snow
sedimentation flux. This work focuses on the assessment of some uncertainty
sources associated with radar measurements:
- absorption by the atmospheric gases, e.g., molecular oxygen, water vapour, and nitrogen;
- attenuation due to the presence of a highly reflecting structure between the radar and a "target structure".
RSM results for a simplified meteorological scenario, consisting of a humid
updraft on a flat surface and four cells placed around it, are presented. |
