Special Issue Information

Dear Colleagues,

Tremendous advances have been made in the last 30 years in the science, technology, and engineering of radars. With the development of multiple polarization, multiple wavelength, and network sensing technologies, the radar has become a widely used tool in meteorological and hydrological applications. Radar can provide the information needed for weather systems, weather forecasting, flood warning, and climate surveys.
The goal of this Special Issue is to share the recent advances in radar meteorology and hydrology. Topics of interest include, but are not limited to, the following areas:

  • New radar system concept for precipitation observation;
  • Advances in radar signal processing and quality control;
  • Cloud and precipitation microphysics;
  • Remote sensing precipitation measurement;
  • Radar meteorological and hydrological applications;
  • Remote sensing applications in climatology.

You may choose our Joint Special Issue in Remote Sensing.

An automated quality control pre-processing algorithm for removing non-weather radar echoes from airborne Doppler radar data has been developed. The proposed algorithm can significantly reduce the time and experience level required for interactive radar data editing prior to dual-Doppler wind synthesis or data assimilation. As important as reducing the time required and skill level necessary to process an airborne Doppler dataset can be, the quality of the automated analysis is paramount. Retrieved wind data, recovered perturbation pressure data (with associated momentum check values) and correlation coefficients were computed. To quantitatively test the quality of the automated quality control algorithm, spatial Pearson correlation coefficients and momentum check values were computed. Four different (published) Electra Doppler Radar (ELDORA) datasets of convective echoes were used to stress the algorithm. Four distinct threshold levels for data removal in the automated quality control algorithm were applied to each of four ELDORA datasets. The algorithm threshold levels were labeled as follows: extremely low, low, medium, and high. Extremely low algorithm cases were deemed necessary during the data analyses and were added to the low, medium and high cases. A description of each case and the differences in the perturbation pressure momentum check values and correlation coefficients between the interactively edited fields were computed. These comparisons along with a subjective visual inspection show that the automated quality control algorithm can produce an analysis comparable—and in some cases superior—to an interactive analysis when used properly. A key benefit of this algorithm is that the skill level of a relatively inexperienced airborne radar meteorologist may be effectively increased by using the SOLO QC algorithm. Full article
