UWEC Auto  

Definition

  • The second mobile platform deployed for LMOS 2017 was the UW-Eau Claire automobile1367 platform, equipped with a 2-B Technologies Personal Ozone Monitor and a handheld Kestrel weather sensor. This platform made regular measurement stops between the Grafton WDNR site and the Sheboygan Spaceport site to investigate N-S and shallow E-W gradients. The ozone measurements were taken at a height of 3 m for at least 5 minute increments at each location. The 15 stops are described in 1371 Table 2.6.2. On June 2, 3, 12, 13, and 17 the UW-Eau Claire vehicle drove the route of some combination of the stops (e.g. Stops 1-13 on June 2, Stops 10-15 multiple times on June 3 to correspond to ship and aircraft measurements made concurrently). Data from the ozone monitor was obtained using 1 minute averaged signal. The duty cycle of the Personal Ozone Monitor subtracts a background (scrubbed ozone) UV-signal from a whole air sample, which accounts for the UV absorption of water. However, drastically changing humidity can lead to higher standard deviations in this instrument, which is why the vehicle chose to stop at a single location to measure ozone. (en)
