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.

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.

Meteorological Report for July 2019, NearSys Station

A little late, but better than never. It's warm and dry. So the air temperature cools down nicely after sunset. In fact, most nights we don't need air conditioning after dark.

Air Quality for NearSys Station, 28 July to 3 August 2019

I split these reports up at the change of the month. Although Boise had bad air quality on Thursday, that smoke did not reach NearSys Station.






Only the first two days of August are in this data run.
