At the Fifth Ionospheric Effects Symposium, a paper was presented and published that described an operational Air Force Weather Service AWS, near real-time, ionospheric specification model called Ionospheric Conductivity and Electron Density ICED. That version of the model specified primarily the northern hemisphere midlatitude and auroral zone ionospheric regions and did not cover either the low latitude or high latitudepolar cap regions. We are making extensions and modifications to ICED that provide a global specification - in effect a GLOBAL ICED. Major additions include 1 specifications of electron and ion density profiles 90 to 1000 km in the high latitude trough, auroral oval, and polar cap ionosphere in both northern and southern hemispheres, 2 midlatitude electron and ion density profiles that include magnetic declination effects, and 3 low latitude ionospheric specification that accounts for longitude control through differences in vertical E x B drift patterns. Since this model is driven by real-time data, we describe the various input parameters and how they are incorporated.
