Zdr Bias Determination for S-Pol during 2014/2015 Test Phase (MASCRAD, FRONT-DE)

The following represents a summary of Zdr bias determinations from vertical pointing, during the initial FRONT-DE and MASCRAD experiments, right through to tear-down prior to PECAN.  The radar was in "test mode," with relatively little attention paid to changes that might affect the calibration of the radar system.  It is expected that Zdr bias will not be constant during the time period shown, and the information is provided for completness, only.

(See the page https://www.eol.ucar.edu/content/zdr-bias-determination-s-pol-pecan, for some details on Zdr Bias Determination).

A full set of bias histograms can be found here. (Note: the Drupal "advanced import" for a gallery scrambles the order of the plots)
