Summary
Ionospheric Total Electron Content (TEC) determined from July 1991 to June 1995 is examined from southern Australia using Global Positioning System (GPS) satellite data recorded by the Defence Science and Technology Organisation at Salisbury, South Australia. Midday TEC was observed to increase with sunspot number. Protonospheric TEC was estimated from the difference between GPS TEC and TEC determined from Faraday rotation measurements. Ionospheric slab thickness from 1991 to 1993 (when protonospheric TEC was negligible) showed no substantial latitudinal variation for each season and year. Midday slab thickness is greater in summer and is greater nearer to solar maximum.
