Abstract
This paper provides a theoretical calibration of Optical Array Probes (OAP) mounted on a given aircraft, in order to take into account the aerodynamic influence of the entire aircraft on the measurements obtained. The measured parameters are corrected through the computation of the air flow-field around the entire aircraft carrying the probes, for different flight conditions, in order to obtain the corresponding undisturbed values. These undisturbed values have been compared to the microphysical ones computed by an atmospheric model, the Regional Atmospheric Modeling System (RAMS). It was found that the removal of the disturbances made by the aircraft on the atmospheric conditions is feasible and provides data that compare much better to the model results. It is suggested that such kind of airborne data corrections may be performed in order to improve the quality of the observations if the aircraft and probe geometries are known. Further information regarding the best location of the probes on the considered aircraft is also obtained.
