Rain rate question
Posted: Tue 27 Dec 2011 7:57 am
I download from the station logger at 10 minutes intervals and it seems that the rainrate that is calculated is too low. Examples
Rain recorded in 10 min period, Rain Rate Calculated, Should it be this 10 minute recording increased by a factor of 6 (10 minute per hour)
0.5, 0.9, 2
1.0, 1.9, 4
1.5, 2.8, 6
2.1, 3.7, 8
It just seems when I get for example 0.5 it is only a rate of 0.9. I know it hard because the station does not supplies it but at some stage unless the calculation is at its best maybe could be improved. I did a quick search and there has been previous trouble but note that I am not running Cumulus all the time and only at 10 min intervals from the station logger which may make a difference. How is it calculated, that would help to know. Or am I not seeing this right. There is website in the same suburb as me that reports correct rate but that is the Fine Offset which I think also has be calculated from that type of station. Would it be possible at some stage to do a similar calculation for the La Crosse, unless the calculation is correct.
Just a question. Thanks
