This temperature recording project began in September of 2006. Except for a several day outage after the earthquake later in October of '06, the data has been reliably recorded every two minutes, 24 hours a day. A new outside temperature sensor was install in a better location in October of 2007. This sensor more acurately senses the outside air with much less interference from the building. The data below is taken from this sensor.

Red - This plot marks the warmest temperatures recorded for this day of the year since October of 2007.

Blue - This plot marks the coolest temperatures recorded for this day of the year.

Grey - This is the mean temperature plot for this day of the year.

Black - This is today's temperature plot.

This data is the same as the top graph, but showing a week's worth of data.

This graph shows two sets of data.

The upper set of data shows the maximum temperatures recorded:  The black line shows the maximum daily temperature for the current year.  The red line (if visible) shows the maximum of daily high temperatures for all years recorded.  The grey line is the average of all daily high temperatures by date.

The low set of data shows the minimum temperatures recorded.

Cooling Degree Days, 64.4 is the reference point
