I built a sunshield for the Amprobe temperature and relative humidity datalogger. So these data were recorded in the backyard. Interesting temperature spike and abrupt drop in the relative humidity near midnight.

24 Hour Temperature and Relative Humidity for NearSys Station, 29 July 2018

Temperature and relative humidity was collected on the front porch for 24 hours. Below are the results.


Changes in Temperature and Relative Humidity at Flight Level 4 AGL

On the 29th, the UAVSonde was launched three times to collect air temperature and relative humidity data. The data show the air temperature remaining nearly constant on the ground until the late afternoon. The air temperature aloft increased significantly in the late afternoon. This unexpect result means I need to refly this mission again and with more flights.


The relative humidity on the ground decreased through out the day; but aloft, it increased slightly by evening.

Visibility for NearSys Station, 29 July 2018

The UAVSonde was launched three times on the 29th to evaluate how the visibility and conditions at flight level 4 changes over a 12 hour period.

In the morning, the visibility was in excess of 30 miles, but less than 50. By 8:00 PM MDT, the visibility had increased to right at 50 miles. This is because the warmth of the day had lifted the smoke infiltrating the Treasure Valley.
