Vertical profiles of Ozone concentration collected by an Unmanned Aerial Vehicle and the mixing of the Nighttime Boundary Layer over an Amazonian Urban Area

The nighttime boundary layer was studied in an urban area surrounded by tropical forest by use of a copter-type unmanned aerial vehicle (UAV) in central Amazonia during the wet season. Fifty-seven vertical profiles of ozone concentration, potential temperature, and specific humidity were collected f...
