AB: Perturbations in the daily averages of the `true' neutral atmospheric densities have been derived from High Accuracy Satellite Drag Models (HASDM) at different perigee heights of the satellites during disturbed periods of 2001/02. A Mulltiple Linear Regression Analysis is then performed on daily averages of Ap indices and the perigee latitudes to predict changes in the `true' neutral densities in response to geomagnetic disturbances. The results and limitations are discussed.
