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.
