Accuracy of Weather Stations and the poor resolution in Wunderground software

Those of us with expensive and accurate Weather Stations reporting to Wundergground expect to see display results matching what the Weather Bureau of Meteorology (B.O.M. in Australia) sensor accuracy is and the resolution displayed.
As an Example my Davis 6163AU Vantage Pro 2 Plus with it's 24 Hr aspirated outdoor temp and humidity sensors specifies an accuracy of +/-0.3 Deg C with 0.1 display resolution for the Temp out of the box.  When Calibrated via an offset in the console to a standard it will be as accurate as B.O.M. in Australia.

IBM / WUNDERGROUND...Please look at this link and see how weather should be reported for Temperature and other measurements.

Please relay this link to Wunderground software engineers that appear not well educated in weather reporting so that Wunderground can be professional in its reporting and all the negative comments exponentially increasing will be gone and a happy Wunderground restored.

Thank you for your comments on temperature decimal display. 

I believe that this IBM Department is not internationally minded as far as units are concerned. Another example is the fixed Graphtimeline as noted as12 hour am/pm System. One gets used to it.

Well done IBM,  Finally we have the decimal place which is needed for Celcius readings in Australia and graphs looking much better with 0.1 readout..  Lots of happy Weather station people now inc me.
There are a few other errors that still need to be fixed like rainfall from my Davis is in 0.2mm increments yet WU makes magically converts it to 0.25mm giving an accumulated error. I assume some sort of imperial/metric conversion error.
Keep up the good work maybe though in not so long a time frame.

Yeah it's good to see those meaningless decimal places... It made a whole bunch of people happy... makes everything look like there is more since involved than there really is.

William. I think the decimal points are a whole lot more meaningful than your worthless comments. I think you should definitely put some rubber tape on the display and cover them up so they don’t offend you so much.

Huh.  Really?  What model of weather station do you have?  Let's check the specifications to see what the actual precision and accuracy of the temperature measurement is before making uneducated statements.  Remember, physics will actually still hold in your back yard too.

William read my 1st Post it is all in there.  +/- 0.3Deg C Accuracy, Aspirated. Set up similar to B.O.M a Govt Weather station in Australia. I have 1/4 Acre property.

We need the decimal place in Celcius to get your +/- 1 Deg F accuracy. In Australia we are metric. If you feel a decimal place in Celcius isn't needed then look at all the Govt weather station reporting in Australia. Try argue with them !

So happy now. Thanks to the programmers and to the managers supporting us with our wishes on displaying Celsius Degrees with Decimals. "A giant leap" towards internationalisation. Auguri!
