As part of a Research Experience for Undergraduate (REU) program internship, an X- Band weather radar and S-band weather radar were used to collect dual-wavelength data for analysis and comparisons between Phidp, Kdp, and rain rate estimation for both radars. These radars are both located at the CHILL facility in Greeley, CO and the experiment took place during the summer months of 2010. This experiment looked at well behaved rain targets and established similarities between the polarimetric parameters obtained from both the X and S- band frequencies. In the future, a common gridpoint analysis will be made to compare the Kpd and the Kdp-based rain rates observed at two different wavelengths. The data collected occurred over several days which had a rain target within 40km.
