Scientists from TU Delft’s ATMOS group have devised a novel method to estimate the differential backscatter phase and the differential propagation phase from polarimetric weather radar measurements.
These differential phases do not suffer of attenuation and they do not depend on the absolute radar calibration. Therefore, this method opens amazing new horizons for meteorological radar polarimetry such as:
- rain rate estimation and raindrop-size distribution estimation without the need of an absolute radar calibration,
- operational absolute radar calibration by precipitation measurements,
- attenuation correction including the estimation of wet radome attenuation,
- and more …
The method will be presented for the first time at the European Conference on Radar in Meteorology and Hydrology which takes place in Sibiu, Romania, the 6th – 10th of September 2010. » Conference Homepage
