There were some missing/incomplete elevations in the data (which required code workarounds) and most of the data had some required fields for computation of the radar bin positions that were either set to bogus or fill values. There were a few "working" files that seemed to have the values we needed set properly, so I cross referenced those variables in the cfradial files and compared their values between the working and non-working CPOL files. I found that the following variables were causing a problem with our beam geometry calculations:
Variable | Working value | Broken value |
---|---|---|
pulse_width (array) | 1.02e-6 | -512 |
radar_beam_width_h | 0.92 | -512 |
radar_beam_width_v | 0.92 | -512 |
ZDR is a noisy parameters, and it causes the rainfall rate distribution to be quite largely spread when using ZDR to compute the rainfall.
A way to correct this would be to perform a 5-gates window averaging on ZDR data before computing the rainfall rate.
