I've studied error theory and can see several areas error in the procedures. <br /><br />When measuring snow depth on the snow board, there's potential for judgment error of the placement not subject to wind erosion and drift. Also refraction error (being unable to get a perfect eye level) and snow displacement from the yard stick being placed in the snow. It seems each one of those error bars would be more than 1/10th". I don’t know if it’s significant but there's also temperature expansion and retraction as there is with metal tapes we use for land surveying. <br /><br />In the picture of the guy holding the glass gauge and reading to the nearest 1/100th it appears he wasn't holding the glass level making those error bars several hundredths. <br /><br />When I first read the 14.2” second to 15”, I wondered if they were measuring the same thing. I also notice that most of the amounts from the smaller towns and rural areas are reported to the nearest inch which I think are more relatively accurate. <br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7965215084022057128.post-85459202541628907022013-02-26T14:13:39.043-06:002013-02-26T14:13:39.043-06:00@donndublin: Everything you wanted to know about ...@donndublin: Everything you wanted to know about snow measurement but were afraid to ask: http://www.cocorahs.org/Media/Training/Training_Snow.html<br />Brianhttps://www.blogger.com/profile/08331066509646364037noreply@blogger.comtag:blogger.com,1999:blog-7965215084022057128.post-76574215296421926442013-02-26T11:27:29.818-06:002013-02-26T11:27:29.818-06:00Mike,

I find it difficult to see how snow accumulation can be measured to the nearest tenth of an inch.<br />In surveying we measure ground elevations to the nearest tenth of a foot. <br /><br />What do the error bars look like with mearsureing snow depth?<br /><br /> <br /><br />Anonymousnoreply@blogger.com
