Heavy rain over S Yorks/Derbys/Staffs this evening, GB3ZEM signal was enhanced by 3-5dB but also had 25Hz of doppler spread, which I think must be rain scatter.  That spread would come from a few metres per second effective path length change.  At 2.3GHz, large drops of 5-6mm start to be large enough to cause significant scattering.  Interesting that the aircraft scatter was not obviously affected by the RS.  Looks like a couple of big radar splats across the whole spectrum as well.

Later this evening, the rain had gone and we are back just about to normal.  Still lots of aircraft scatter as usual
