Results of a Comparison between the Lindau Foil Cloud Experiment and the Inflatable Falling Sphere Experiment.
Abstract
Between 10 and 24 April 1974, a series of rocket flights was launched at White Sands Missile Range as part of a cooperative project between the Arbeitsgruppe D-Schicht-Aeronomie of the Max-Planck-Institute fur Aeronomie and the US Army Atmospheric Sciences Laboratory. Primarily, the purpose was to compare wind sensing techniques in the height range between 95 and 80 km. In addition, the foil chaff clouds are capable of providing neutral air density over the height interval from 85 to 92 km. The inflatable falling sphere experiment is capable of deriving density, tempeature, and wind data between 35 and 90 km, with less accuracy above 85 km. The foil chaff cloud is primarily intended to measure winds and wind shears between 95 and 75 km with good height resolution due to its low fall velocity. The foil chaff can also be used to determine density, pressure and--within certain limits--air temperature for smaller height interval from 95 to about 85 km. However, some assumptions have been made in deriving the additional thermodynamic data. (Author)
