Abstract

Monitoring the atmospheric conditions is one of the main activities in Aerospace Meteorology. During the launch spacecraft operations, measuring the wind at various atmospheric layers is crucial to mission success. In the Alcantara Launch Center operates a Wind Profiler (WP) Vaisala LAP-12000 which provides vertical profiles of wind between 1500 and 6000m of altitude, in layers of 145m, at intervals of 10 minutes. This study conducts a statistical analysis over one year of data obtained with WP by comparison with Vaisala RS92SGP radiosondes (RS). Correlation (ρ) analyses were performed on wind speed and its zonal and meridional components; and mean and standard deviation (σ) of the differences between the zonal and meridional components. The results has shown a strong correlation between the data acquired with both instruments, with ρ > 0,75 and σ 6 3m/s in all performed analyses.
