Weather radar and hydrology

Weather radar rainfall data in urban hydrology

Application of weather radar data in urban hydrological applications has evolved significantly during the past decade as an alternative to traditional rainfall observations with rain gauges. Advances in radar hardware, data processing, numerical models, and emerging fields within urban hydrology necessitate an updated review of the state of the art in such radar rainfall data and applications. ...

Synthetic Aperture Weather Radar

Remote sensing applications to hydrology; imaging radar

Synthetic Aperture Radar (SAR) data are very useful for hydrological studies because the dielectric properties of materials are generally dependent on the amount of liquid water in the material, and this affects the strength of the radar backscatter, a°. Additionally, the ability of microwaves to penetrate the surface of many materials often permits analysis of subsurface properties. Further, S...

The Danish weather radar network

The Danish Meteorological Institute (DMI) operates four cband radars for weather monitoring. Three of these radars are doppler and were purchased from Electronic Enterprise Corporation (EEC) in the last 2 – 4 years. The fourth radar is an older non-doppler radar manufactured by Ericsson of Sweden and is situated on the island of Bornholm in the Baltic Sea. Geographical location of the radar sit...

ERAD 2010 - THE SIXTH EUROPEAN CONFERENCE ON RADAR IN METEOROLOGY AND HYDROLOGY Online Determination of Noise Level in Weather Radars

All receivers detect signals that are at some level above the limit imposed by the random voltage (i.e., noise) inherent in every electronic device. Consequently, proper measurement of noise power is of paramount importance for censoring of the weather radar data, which, in turn, is essential for the correct operation of automated algorithms and accurate forecasts derived from such data. Presen...
