Abstract
This study attempts to correct the attenuation of the radar reflectivity factor from two X-band radars in Cyprus, using a constrained attenuation correction method. This research was implemented under the assumption that the difference between the reflectivity measured by each of the ground radars, on the one hand, and the reflectivity measured by the Global Precipitation Measurement (GPM) mission, on the other hand, equals the path integrated attenuation (PIA). This is because solely the reflectivity data at horizontal polarization have been used so far. Various parameter combinations of linear coefficients for the constrained correction were tested empirically, using GPM DPR data as a reference. The results showed that no single parameter combination can be consistently effective, and highlighted the need for event- and radar-specific attenuation correction.
期刊介绍:
The journal publishes scientific papers (research papers, review articles, letters and notes) dealing with the part of the atmosphere where meteorological events occur. Attention is given to all processes extending from the earth surface to the tropopause, but special emphasis continues to be devoted to the physics of clouds, mesoscale meteorology and air pollution, i.e. atmospheric aerosols; microphysical processes; cloud dynamics and thermodynamics; numerical simulation, climatology, climate change and weather modification.
