PRISM: A Parameterized Real-Time Ionospheric Specification Model, Version 1.5.
Abstract
This report describes PRISM Version 1.5, a parameterized, real-time ionospheric specification model. PRISM was developed for use at the Air Force Space Forecast Center (50th Weather Squadron) at Falcon Air Force Base. PRISM consists of the theoretical climatology model, PIM (Parameterized Ionospheric Model), and an algorithm for updating PIM electron density profiles using ground based an spaced data. PIM is based on a set of diurnally reproducible runs of theoretical ionospheric models for broad range of geophysical conditions and for three seasons (June, December, and March/September). PRISM is capable of ingesting and utilizing data from digital or analog ionosondes, polarimeter or GPS based TEC measurements, in situ plasma measurements (electron density, electron temperature, ion composition, ion temperature, and plasma drift velocity), and auroral electron and ion precipitation measurements. PRISM 1.5 contains a number of improvements over PRISM 1.0, which was described in PL-TR-91-2299, including improved climatology, improved handling of in situ plasma data, and the ability to ingest and utilize TEC data.
