This project comprises five separate elements that address science and education objectives of the HAARP program. These elements are: (1) To establish the characteristics of the ionospheric source region responsible for the ELF/VLF waves generated by modulation of HAARP HF emissions, and to measure the ELF radiation pattern. (2) To attempt to stimulate hydromagnetic waves in the onospheric waveguide using the HAARP heater. (3) To develop a simulation model for the plasma physical and electromagnetic ffects of localized ionospheric heating with the purpose of predicting outcomes of heating experiments and to guide the design of ew experiments. (4) Using the SuperDARN instrument on Kodiak, to examine the formation of ionospheric irregularities within the heated volume and the relationship of the irregularities to other observations such as the generation of Stimulated Electromagnetic missions. (5) To provide scientific education about HAARP and physical science in general to members of the local Copper Valley ommunity. In this report the results of research obtained to date in each of the five program elements are reviewed, and ecommendations for follow up activities are presented.
