Modified rain gauges and the wind...
« on: April 04, 2009, 04:18:35 PM »
A short while ago in a different thread I mentioned
Over the months, the WMR200 consistently reports approx 6-7% more rain than the WMR928. That could just be natural variation, or that the 928 suffers more "blow over" due to its modified design, or it could be a side effect of these strange figures. Hard to be sure.

Today I've had sort of confirmation of the suspected wind effect. For a good few hours we had the unusual (for here) combination of prolonged rain and low windspeeds (only occasionally over 5mph). During that time the two rain gauges tracked each other closely, with the (modified to 0.25mm tip) WMR928 finishing the shower on 23.25mm and the (unmodified) WMR200 finishing on 23.10mm.

Maybe I should get on with trying the "wind calming" measures that I've had in mind for a while for around the WMR928 gauge...

Is there anyone else here with both a modified and unmodified gauge? If so, what do you find?
