¹ Rain season: July 1st to June 30th. We keep extraordinary precise measurements of our rainfall. All of our rainfall is backed up daily by two separate professional rain gauges that are THE standard in the weather industry. During the fall & early spring when the oak tree leaves fly in the fall or oak flowers in the spring, the main rain guage for our Davis VP Pro+ Weather Station can get plugged up with leaves, pollen & debris. We then carefully measure the rain in our backup gauges and adjust the rainfall totals accordingly. The clogging up is worse in the spring with the oak flowers/pollen than in the fall. So if you see the rainfall totals unexpectedly jump up, then it was most likely due to our manual rainfall adjustment.   ² When there is measurable rainfall for the day, 3 separate data fields appear, the average hourly rainfall rate (Rain Rate /hr), the average hourly rainfall rate high for the day (Rain Rate High /hr) and the total rainfall for the storm (Storm Rain). Otherwise precipitation for the last 7 days, the highest rainfall day on record & number of days since the last precipitation are used. Day record is the most rainfall amount on any 24 hour day at the station since 6/22/2006.).   ³ Air Quality Index is provided by Minnesota Polution Control Agency and is updated hourly between the hours of 6AM and Midnight.   ⁴ Solar Index represents either an absolute scale of solar energy (W/m²) using the station’s recorded maximum or a percentage of computed theoretical solar maximum using the station’s location and time of day. These indices differ most when the sun is low on the horizon. The current scale is shown, and will toggle if it or the icon is clicked.   ⁵ Beaufort wind force number and Beaufort scale in text).   ⁶ Estimated amount of water needed to replace the water used by plants and evaporation from the past week.

Data Measurement Information: As with many locations in the foothills, trees can be a factor in the mornings and later in the afternoon for measurements such as Wind, Solar & UV. Particularly in the cold season when the sun is low on the horizon. Our anemometer is 26 feet high, but still wind runs a few mph lower than normal in a couple directions where trees are present, which is accurately adjusted for. Our station data records go back to June 22, 2006, 9 years of Placerville data as of this writing. Normals & Records are based on downtown Placerville historic records dating back decades, not from this stations shorter term data. We do however use our own historic station data in many other instances.
