First estimates of HF‐induced modifications of the D region by the HF Active Auroral Research Program facility

A one‐dimensional, self‐consistent computer code was used to predict electron temperature and density changes in the lower ionosphere caused by high power, high frequency (HF) radio wave heating. The code was used to obtain first estimates of ionospheric perturbations due to the proposed HF Active Auroral Research Program (HAARP) heating instrument, which is currently in the early phases of construction. Simulations were conducted using both pulsed and continuous wave (CW) heating modes, under a variety of conditions. Results indicate that electron temperatures will be increased by up to a factor of 15, and electron densities will be changed by up to 50%relative to natural levels.

National polar radio science consortium

The National Polar Radio Science Consortium (NPRSC) was established in 1991 to represent the radio science community's interest in the High‐Frequency Active Auroral Research Program (HAARP). The HAARP project is cosponsored by the Office of Naval Research (ONR) and the Air Force Philips Laboratory (AFPL). The primary goal of this consortium is to ensure maximum participation and maximum usability of the HAARP instrument by the scientific community.
