24-Hour Photometer for NearSys Station, 13 September 2019

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.



24-Hour Temperature and Relative Humidity for NearSys Station, 13 September 2019

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.

Air Quality for NearSys Station, 1 - 6 September 2019

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.

24-Hour Photometer for NearSys Station, 3 September 2019

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.


24-Hour Temperature and Relative Humidity for NearSys Station, 3 September 2019

The relative humidity reached 100% as the dew formed after midnight. Otherwise, an uneventful day.

Air Quality for NearSys Station, 27 - 31 August 2019

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.

24-Hour Air Temperature and Relative Humidity for NearSys Station, 25 August 2019

The temperature and relative humidity sensor are shielded from direct exposure from rain, to an extent. At around 3:00 PM, the sensor and its housing got doused with water from a lawn sprinkler. Hence, the brief change in temperature and relative humidity.


24-Hour Photometer for NearSys Station, 25 August 2019

I placed the LED Photometer in the wrong location this week. So the photometer got sprayed with the lawn sprinkler during one of its watering sessions. The sky didn't actually go dark at 2:00 PM.

24-Hour Photometer for NearSys Station, 18 August 2019

Odd spikes again in the ultraviolet. I wonder if this is seasonal? The detectors are LEDs and do have some directionality in their sensitivity. The 10:30 AM drop in green intensity is unusual also.




24-Hour Temperature and Relativity Humidity for NearSys Station, 18 August 2019

Nothing unusual on the 18th. But the temperature did drop low enough to reach 100% relative humidity shortly before sunrise.

A clear day without clouds. Interesting spikes in UV-B, however. And interesting to note that the time for peak intensities for each spectral band wasn't the same. 


24-Hour Temperature and Relative Humidity for NearSys Station, 12 August 2019

It got cool enough over night to reach 100% relative humidity. Otherwise, nothing unexpected for a mid-August day - very dry during the day.
