Use the drop-down lists to set the variables for the field, station and month you are interested in. Be sure to specify which averaging interval you prefer (hourly or daily). Once you've selected a month the data will load. If you want an entire year of data click the "Show Entire Year" check box. The data will be loaded from the database and shown in a table on the page. The data are also available as text and CSV files. The links to these files are (will be) given in the table header. Please be patient while the data loads and the graph draws it.

Data is collected minute-by-minute on the network (at almost every site) so hourly averages are usually made from 60 observations and daily averages are composed of 1440 observations. Where raw data is missing the count column will show the reduced number of observations. Where there is no data at all in the averaging period the time interval will be blank.

Rain observations are also included now. When the weather stations that we use notice that it is past midnight (the second minute of the day) they reset the daily total rain amount to zero. This means that the daily maximum value is recorded as the first value each new day. In order to hide this quirk of the hardware we ignore, for the raintotals, the first ten minutes of each day. This is done for the daily rain amounts and the hourly rain if the hour is the first hour of the day. It will only affect the minimum and average rain amounts in those intervals and will not affect the maximum. Since it is typically maximum rain that most people are interested in for a particular interval of time, this is not a serious problem.

The plot is live. You can zoom in by clicking and dragging a mouse over the graph. You can zoom back out by double-clicking on the graph. Moving the mouse cursor over the graph will highlight the value nearest to the mouse. If you want to smooth the data change the value in the lower left of the graph. It gives the number of consecutive data points that should be averaged together before the curve is drawn.

The dygraphs plot, written with Javascript, is claimed to work on Internet Explorer. My tests don't support this claim (IE 8 seems to fail, IE 9 is OK). Since it does seem to work with Firefox, Chrome and Safari on both the MS Windows and Max OS X platforms as well as Linux where applicable we are just not going to worry about it.
