Comparative Investigation of High-Latitude Ionospheric Structure and Effects Near Solar Maximum

Abstract

Northwest Research Associates (NWRA) has recorded a database containing measurements of the intensities of two L-band signals transmitted by satellites of the Global Positioning System and the differential carrier phase and differential group delay between them. Data collection was carried out during the period December 1990 - December 1992, which immediately followed the recent solar maximum. Data collection equipment, operated and serviced by NWRA, was located at Hanscom AFB, MA; Lerwick, Shetland Island, UK; and Thule AB, Greenland. Software tools to test, quality check, reduce, analyze, and display the data were developed. The total electron content data from the sub-auroral station (Lerwick, Shetland Island, UK) have been well analyzed and are shown to provide extremely detailed morphology for all times, seasons, and levels of magnetic activity. A log detailing the availability of data according to date, site, receiver type, and data quality is included herein.
