AB: This paper describes a combination of novel technologies that enable the collection of atmospheric data, including PTU, wind speed / direction, and carbon dioxide concentration, from ground level to a maximum of 2.5 kilometers height above the ground using temporarily placed equipment. The measurement platform is a portable, highly engineered tethered balloon system that is used to loft and recover one or more instrument packages at controlled ascent and descent rates into the atmospheric boundary layer. Carbon dioxide concentration is measured with a lightweight NDIR instrument that is diffusion aspirated, self contained, and requires only one watt of power for operation. A test flight of the system is described and atmospheric data from the flight is shown.
