Abstract
The response of the ionospheric E-region to solar-geomagnetic storms can be characterized using observations of infrared 4.3 um emission. In particular, we utilize nighttime TIMED/SABER measurements of broadband 4.3 um limb emission and derive a new data product, the NO+(v) volume emission rate, which is our primary observationbased quantity for developing an empirical storm-time correction the IRI E-region electron density. In this paper we describe our E-region proxy and outline our strategy for developing the empirical storm model. In our initial studies, we analyzed a six day storm period during the Halloween 2003 event. The results of this analysis are promising and suggest that the ap-index is a viable candidate to use as a magnetic driver for our model.
