[MIS13-P05] Comparison of vertical structure of storms by satellite-borne dual-frequency precipitation radar and dual polarized phased array weather radar
Keywords:weather radar, satellite-borne radar
Satellite-mounted radar, which is capable of global observation, is indispensable for observing precipitation phenomena on a global scale.
However, satellite-mounted radar is much difficult to calibrate because it locates in space.
Therefore, we compared the accuracy of radar reflectivity observations with those of ground-based radars, which are relatively easy to calibrate.
The Dual-frequency Precipitation Radar (DPR) onboard the main satellite of the Global Precipitation Measurement (GPM) project was used as a satellite-borne radar, and the Dual-frequency Precipitation Radar (DFR) with high temporal and spatial resolution was used as a ground-mounted radar. Dual-polarization Phased Array Weather Radar (MP-PAWR), which has high temporal and spatial resolution, was adopted as a ground-based radar.
Since the sample size of the DPR is smaller than that of the MP-PAWR, the sample size was standardized by taking a weighted average of the MP-PAWR observation data.
Because ground-mounted radars can be affected by clutter from surrounding terrain and structures, we compared not only the horizontal but also the vertical direction of the radars.
