Correlation coefficient and precipitation type
Notes:
Dual polarization radar data was very helpful for identifying rain vs. snow vs. mixed precipitation boundaries through the event. The rain / snow boundary at 06z on March 30th can be clearly seen on the image on the left, indicated by the lower values of correlation coefficient. A boundary between snow and mixed precipitation can be seen at 00z on March 31st on the slide on the right, again indicated by lower values of correlation coefficient.
