IPIX Radar	Dartmouth	Grimsby
	the Grimsby database
What's online | What's not online

In winter 1998, a database of high-resolution radar measurements was collected using the McMaster IPIX radar in Grimsby, on the shore of Lake Ontario, between Toronto and Niagara Falls. The 222 data sets in this database focus specifically on the presence of floating objects (targets) of varying size, seen at various weather circumstances. The IPIX radar has been upgraded since the measurement of the Dartmouth data in 1993. The dynamic range has improved to 10 bits (was 8 bits), so that strong target and weak clutter signals can be observed simultaneously without clipping or large quantization error.

As yet, the information on Grimsby data is not complete, and only included for comparison with the Dartmouth data.

What is online:

• Graphical display of all 222 datasets. Pictures include radar return plots and time doppler spectra.
• Map of the data collection site.

What is not online:

• The actual Grimsby data files are stored on 16 CD-ROMs. To obtain these files you are invited to contact Simon Haykin. A subset of the Dartmouth data base is available online.
