Analysis and Comparisons of Inverted Meridional Winds From Space-Borne Measurements of (OI) 5577A
Abstract
This thesis provides a database comparison and analysis of daytime lower thermospheric (E-region) inverted meridional winds. This inversion technique was previously developed (Nardi, 1991) to retrieve the true wind at altitude from OI 5577 A measurements from the DE-2 Satellite's Fabry-Perot Interferometer. The inversion technique is briefly discussed in this study. The raw DE-2 satellite data is processed to obtain spectrograms. This data is processed further to obtain brightness and line-of-sight winds and wind errors. For daytime 5577 A emissions, these line-of-sight winds are averages over two emission layers. The purpose of the inversion technique is to 'unaverage' these winds through an onion peel method on the brightnesses and through a least squares fit to chapman layers on the volume emission rates.
