Analysis and Modeling of AFRL 'Gap 98' Balloon-Borne Measurements
Abstract
This report results from a contract tasking Office or National Establishment for Aerospace Research (ONERA) as follows: The objective of this project is to validate data collected on a French research balloon ('SPIRALE') successfully flown from Gap on 29 June 99. SPIRALE was funded by CNES/ONERA/INSU and developed by ONERA/LPCE to measure atmospheric trace gases (CO, 03, CH4, H2O, NO2. NO, 002, H2O, HF, and others) from 13 to 35 km. Another test campaign (Gap 98") was conducted during June 98 with AFRL balloon-borne sensors above the Gap-Tallard Aerodrome, in southern France. The contractor shall evaluate previously collected data from both balloon experiments and determine if the measured data validates turbulence and radiance propagation codes at middle altitudes and latitudes. The contractor will complete the following tasks: (1) Determine the ozone profile structure as a function of air mass temperature; (2) Evaluate the possible correlation of measured data with local wind shear and ozone measurements from other instruments; and (3) Model the luminance fluctuation and optical turbulence derived from the temperature fluctuation data.
