Erad 2014 - the Eighth European Conference on Radar in Meteorology and Hydrology
The United States’ Next Generation Weather Radar (NEXRAD) program has deployed a polarimetric upgrade to the WSR-88D network radars. This modification provides new base variables to the operational community and has opened exciting new possibilities for improved forecasts and warnings. One variable in particular, differential reflectivity (ZDR), is critically important to improved precipitation...
متن کاملCalibration of the Polarimetric Nexrad Radar Using Meteorological Signals
Regular operation of weather radar mandates frequent calibration to ensure accurate measurements. Even modest calibration errors in reflectivity factor Z and differential reflectivity ZDR may produce severe deficiencies in the quality of radar products such as rainfall estimates and hydrometeor classes. Radar users, including the Federal Aviation Administration (FAA), rely on high quality weath...
متن کاملDifferential power calibration for weather radar
Dual polarized weather radars, radars that can transmit both horizontal (H) and vertical (V) polarized waves, are becoming more common in the world. Dual polarization is accomplished via fast alternate transmission of H and V polarization or simultaneous H and V polarization transmission. The simultaneous H and V transmit mode is becoming quite popular since a high power, costly, polarization s...
متن کاملQuantifying animal phenology in the aerosphere at a continental scale using NEXRAD weather radars
One of the primary ecological manifestations of climate change is a shift in the timing of events in a species’ annual cycle. Such phenological shifts have been documented in numerous taxa, but data for animals have been derived primarily from human observers rather than networks of instruments used for remote sensing. The potential to use the network of weather radars in the United States (NEX...
متن کاملAbsolute Calibration of Radar Reflectivity Using Redundancy of the Polarization Observations and Implied Constraints on Drop Shapes
A major limitation of improved radar-based rainfall estimation is accurate calibration of radar reflectivity. In this paper, the authors fully automate a polarimetric method that uses the consistency between radar reflectivity, differential reflectivity, and the path integral of specific differential phase to calibrate reflectivity. Complete instructions are provided such that this study can se...
