So, July 1 marks the start of the 2012-2013 rain year, and the end of our 20th year of collecting rain data at our home.
This year I tested a bunch of rain gauges, and have revised the way I record and display data. I'll write another post about the rain gauges shortly, but first, here are links to the data I have available:
- Annual Rainfall Totals - going back to the 1992-1993 rain year
- Daily Rainfall Amounts - starting with the 2011-2012 rain year
I will provide links to those pages in the right side navigation bar as well, so you can find them in the future without having to find this post.
I leave you to draw your own conclusions from the data. I stress, though, that rain fall amounts vary widely over even small distances, and we have nothing like a statistically valid sample to analyze anything over the long term. We use this data mostly to try and assess how our well will perform over the coming year. If we have less rainfall we can bet we'll our well will low on water before the next rain year gets going and the aquifer can be recharged.
Another thing this data helps us understand is our local fire danger. Rainfall that is well spread out in time keeps the vegetation moist and thus less likely to be a problem. 2011/2012 was the first time I recorded actual rainfall amounts by the day and kept them, so we still have a lot to learn here.
I hope this data is interesting and useful to someone other than me.
