ERRORS ASSOCIATED WITH METEOROLOGICAL DATA ABOVE 30 KM,

Abstract

Errors in computed wind velocity due only to random errors in position data as determined by the AN/FPS-16 radar were found to vary from approximately 10 mps at 60 km altitude to 2 mps at 30 km. Errors in the computed pressure and density at rocket altitudes can result from uncertainties in the radiosonde height at the 20-mb level. An uncertainty of 0.6 km in the 20-mb height can result in differences of at least eight percent in the pressure and density values above the 20-mb level. Temperature differences of 2.OC at the 20-mb tie-on level (level of radiosonde and rocket data overlap) yield negligible errors (less than 1/2 of 1 percent) in the computed pressure and density values.
