BOREAS AFM-04 Twin Otter Aircraft Sounding Data

Published by ORNL_DAAC | National Aeronautics and Space Administration | Metadata Last Checked: October 21, 2025 | Last Modified: 2025-09-10
The BOREAS AFM-04 team used the NRC Twin Otter aircraft to make sounding measurements through the boundary layer. These measurements included concentrations of carbon dioxide and ozone, atmospheric pressure, dry bulb temperature, potential temperature, dewpoint temperature, calculated mixing ratio, and wind speed and direction. Aircraft position, heading, and altitude were also recorded. Data were collected at both the NSA and the SSA in 1994 and 1996.
