It's drier this week. Normally we see 100% relative humidity at night.

The nights are humid at Nearsys Station these days. During the day, it's not as dry as it was during summer.

NearSys Station experienced a brief air quality warning this week. For about an hour, air quality was in the yellow category (above 50 but below 100 micrograms per cubic liter). We also lost internet access for about 32 hours.
From the photometer chart you can see that we had close to 12 hours of sunlight on the 21st. After 1:00 PM, cloud cover was more effective at obscuring longer wavelengths of light.

One spike of bad air this week. The PM 10 reading got way too high late on the 7th and early on the 8th.

The day started out clear, but partially cloudy skies popped up later in the day on two occasions. It's interesting to note that after 4:00 PM, not all colors were effected equally.
We hit 100% relative humidity during the night. That's not unexpected, since when retrieved the sensor in the morning, it was covered in dew. However, it appears the second night was drier than the first.

Spiky results with a period of 24 hours. At midnight, the concentration of particulates is at their lowest. They then increase until late afternoon. Odd, I'll have to see if this occurs regularly now.

The sky became partly cloudy in the afternoon. Otherwise, an uneventful day. Interesting to notice is that when the sky became partly cloudy, the temperature and relative humidity sensor responded as expected.

The WiFi I use is a Verizon Jet Pack and it shut itself off for a while during this week's monitoring. Therefore this week's air quality monitoring is truncated.
