[Year 12 IT Apps] FW: Feedback in regard to Rainfall Data

[Russo, Frank R]

Hi Guys thought I would pass on the response I got from Melbourne Water in regard to those weird readings for Frankston North and Somerton for February. A great case study also I have included a few ideas that I was playing around with the data for Frankston North going back to September 2003, to see if the reading had any pattern in it, I feel an Outcome coming on. Please feel free to use the data. The last graph shows the February readings for the last 9 years and even though it was only 5.8mm for this year it was quite possible looking at the February 2009 and 2007 readings.
But not possible considering the other readings for the rest of the state and the surrounding areas. See below.

Hi Frank,

Thank you for your email. Yes you are right that these rain gauges have not been working correctly at both the Frankston North and Somerton sites recently. We have had field technicians on-site to assess the instrumentation, with the Somerton site recently fixed and Frankston North due to resume normal operation soon. These sites both house automatic tipping bucket rain gauges, and data from rain events is transmitted to our database by radio telemetry. It seems that the issue was due to a data transmission error in the system which connects the sites to the radio network. Data is uploaded from our database hourly, but unfortunately this means that data posted to the website is unverified. I will arrange for our website administrator to block dubious data for these sites.

Thanks again for bringing this to our attention.

Please let me know if you have any further questions.

Kind regards,
Jess

Hi Guys, great job you are doing.
Just had a query on the latest Rainfall Data that is displayed on your website. I am using the information with Yr11 students and just wanted to check that the values for Frankston North and Somerton were correct as most places had received 40+mm of rain whilst the readings from Frankston North were 5.8 and 7.8. I understand that the data comes from gauges but could there have been a data entry error?
Thanks I await your reply.
