All data of 2011 from our weather radar IDRA can now be downloaded via the 3TU.Datacentre.
The data is freely available under the CESAR database policy.

Here are some of the events captured by IDRA in 2011 to illustrate the variety of data collected:

December 26th, 2011

IDRA reflectivity measurement of fog

Measurement of weak meteorological  echoes, possibly drizzle.

June 28th, 2011

IDRA Reflectivity measurement, 2011-06-28

Strong precipitation due to the passage of a cold front over the Netherlands.
Note the line of weak echoes close to the radar (in the center of this figure). This line is probably due to insects that are lifted in the air as a result of an up-draught.

June 27th, 2011

IDRA reflectivity measurement of insects        IDRA Doppler velocity measurement of insects

An IDRA measurement of insects. The figure on the right which shows the Doppler velocity measurement demonstrates that insects are a very good tracer for air motion.

Overall, the online available IDRA data for 2011 comprise:

  • data from 349 days,
  • during 554 hours IDRA measured moderate or strong precipitation echoes,
  • beside the processed data also 6863 raw data files are available.

Yann Dufournet will give a talk in the Open Seminar Series of the Geoscience and Remote Sensing Department on TU Delft’s involvement in the HyMEx (Hydrological cycle in the Mediterranean Experiment) campaign.

An integrative approach to studying multi-scale processes responsible for heavy precipitation events in the northwest Mediterranean

"Het klimaat verandert. Het wordt warmer. Minder wolken dus – of juist
meer, omdat er meer water verdampt? Wolkenspecialist professor Herman
Russchenberg van de TU Delft vertelt op 25 maart alles wat er bekend is
over wat wolken doen als het klimaat verandert. …" Lees verder op TU Delft Agenda

What has started in April this year as a successful BSc final year project, is now operationally implemented in our 3GHz profiling radar TARA at the Cabauw Experimental Site for Atmospheric Research.

TARA radar control and signal processor

The new radar control and signal processing unit of TARA uses a MATLAB® script to provide in real-time each three seconds a vertical profile of clouds, precipitation, and wind.
Real-time measurements of TARA updated once per minute are also displayed online.

We have received about thirty abstracts on the state-of-the-art of X-band weather radar technology, radar networks, data processing, and quantitative precipitation estimation. The abstract submission is closed now. The workshop program will include plenary discussions, and, furthermore, we have four keynote presentations scheduled:

The CASA X band radar network.Summary of five years of operation of the end to end system, and the path forward.
Speaker: Prof. V. Chandrasekar, Colorado State University, USA.

X-band Polarimetric Radar Network in the Tokyo Metropolitan Area
– Monitoring and Prediction of Urban Meteorological Disasters –

Speaker: Dr. M. Maki, National Research Institute for Earth Science and Disaster Prevention, Tsukuba, Japan.

Hardware Technologies for Realizing X-Band Weather Radar Networks.
Speaker: Prof. D. J. McLaughlin, University of Massachusetts at Amherst, USA.

X-Band Weather Radar: A hydrological Perspective.
Speaker: Prof. R. Uijlenhoet, Wageningen University, Netherlands.

If you consider to participate at the workshop in order to get the latest results on X-band weather radar research, and to discuss with us the state-of-the-art of rainfall measurements with X-band weather radar, please do register before the 1st of November 2011.

You will find the registration form and all necessary information on the workshop website.

" De TU Delft gaat participeren in het project RainGain, dat recent een
Europese subsidie toegewezen kreeg. Het gaat daarbij onder meer om het
plaatsen van een regenradar in Rotterdam die is gespecialiseerd in
lokale neerslagmeting. Daardoor kan men neerslagpatronen in de stad veel
nauwkeuriger meten en daar het stedelijke waterbeheer beter en
efficiënter op inrichten. Denk aan toepassingen als de slimme sturing
van gemalen, het inzetten van waterberging (de waterpleinen in
Rotterdam) en een lokaal weerbericht… "
