Abstract : Work performed under this contract can be divided into three areas, (1) development and testing of a PC based Scintillation Data Recording System (SDRS) and related analysis software, (2) updating and extending D. Anderson's global ionospheric model for studies concerning the generation and transport of polar cap patches, and (3) implementation of existing and new software utilities on the PC and SUN workstation in support of Phillips Laboratory. Beginning in November 1990, SDRS has been installed at 5 field sites from Thule, Greeland to Ascension Island in the South Atlantic. Modified systems have also become TEC receiving stations for a tomography project and a remote access system designed to report scintillation activity at field sites. New software was developed to extract and display SDRS and TEC phase data on the PC. Two important additions were made to the Anderson model; the Hardy statistical model describes electron precipitation patterns, and production caused by precipitating electrons is based on a parameterized version of Strickland's flux transport model provided R. Daniel.
