An X-band transmitter ($ lambda$ = 3,2 cm) should perform better than an S-band transmitter ($ lambda$ = 10,4 cm) in the remote measurement of snowfall by radar. Comparisons between groundtruth measurements and their radar measured counterparts are done for two similar snowstorms (November 20th and 21st 1986, January 30th and 31st 1987), scanned respectively with an S-band and an X-band transmitter, mounted on the 10 m wide antenna of the Weather Radar Observatory of McGill University; these observations confirmed the hypothesis. A mixed rain-snow precipitation event was also observed on February 21st 1989, using alternatively the X-band and the S-band transmitter on the same antenna during the course of the event; this allowed an almost simultaneous comparison of the transmitters. Modifications to the regular sequence of observation of the weather radar during winter are proposed to take advantage of the potential of the X-band transmitter in the measurement of snowfall.
