Cross-polarized radar reflections from wet snow and ice droplets at weather radar wavelengths

Monitoring of Wet Snow and Accumulations at High Alpine Glaciers Using Radar Technologies

Conventional studies to assess the annual mass balance for glaciers rely on single point observations in combination with model and interpolation approaches. Just recently, airborne and spaceborne data is used to support such mass balance determinations. Here, we present an approach to map temporal changes of the snow cover in glaciated regions of Tyrol, Austria, using SAR-based satellite data....

Synthetic Aperture Weather Radar

Radar Data Quality Control and Assimilation at the National Weather Radar Testbed (NWRT)

Extract main features exhibited in each type of data quality problems, and find proper QC parameters to quantify the extracted features. Monitor and record various QC parameters and related background information (by running the above real-time system). Collect independent observations from multiple sources (Dual-Polarization radar, radiosondes, wind profilers and satellites) for "ground truth"...

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...

Radar measurements of snow: experiment and analysis

This paper considers two specific types of experiments conducted to improve our understanding of radar backscatter from snow-covered ground surfaces. The first experiment involves radar backscatter measurements at Cand X-band of artificial snow of varying depths. The relatively simple target characteristics, combined with an exhaustive ground truth effort, make the results of this experiment es...
