Abstract
Dynamic measurements of atmospheric composition of trace gases at low
altitudes, below the safe zone of manned aircraft operation, can be
carried out with small unmanned aerial systems (sUAS). Herein, the
UKySonde 2, a lightweight sensor package aboard sUAS with low-power
consumption, is employed to measure the mixing ratios of: methane,
propane, butane, carbon monoxide, ammonia, nitrogen dioxide, carbon
dioxide, ozone, and non-methane VOCs. Simultaneously, temperature,
relative humidity, pressure, and 3D position are monitored and aligned
to composition measurements at a 1 Hz sampling rate. This new and
improved analytical system is demonstrated to have 64´ better
analog resolution compared to the previous generation (UKySonde 1)
employed during the CLOUDMAP 2017 campaign. The data to be reported was
collected onboard a fully autonomous 3DR SOLO quadcopter in the San
Louis Valley, Colorado at 2430 m.a.s.l. during the 2018 LAPSE-RATE**
campaign from July 13-19, 2018. The presentation will summarize data
gathered during 112 flights totaling over 18 flight-hours, all conducted
under United States FAA Part 107 and COA for flying up to 914 m above
ground level ( 3344 m.a.s.l.).
