Most of the High Plains Conference this afternoon was devoted to the new dual-polarization (DP) radars. In theory, the DP's should produce much more accurate estimates of the amount of rain falling. So far, in very limited testing, they have not. We have some ideas as to why that is the case and we think it can be fixed.
