On October 10 I gave my Davis weather station an overhaul. The dew point readings seemed to be off and I had ordered and received an overhaul kit from Davis Instruments. The instrument package has been in use since December 2015.

I removed the radiation shield, cleaned the accumulated mildew from the plates, and replaced the temperature/humidity sensor. I also installed a new battery and solar panel. I replaced the rain sensor with a more accurate one. The spikes are to deter birds from clogging the rain collector.

I will work on the wind vane and anemometer in the Spring. They were replaced about 4 years ago.

Two other sensors are also part of the instrument suite. A UV sensor measures the UV index and a solar radiation sensor provides readings of Watts per square meter.

The other part of my weather station is the air quality sensor. Its operation remains nominal. It measures 1, 2.5, and 10-micrometer particulates in units of micrograms per cubic meter.
