VERTICAL-INCIDENCE IONOSPHERIC DATA: THAILAND

Abstract

The Granger Model 911 ionospheric sounder systems were operated during 1966 and 1967 at six sites in Thailand ranging between about 7 and 19 degrees North geographic latitude (geomagnetic field dip angles from 5 degrees S to 20 degrees N). This report presents the results from scaling the vertical- incidence ionograms obtained for foF2, h'F2, foF1, h'F1, foEs, h'Es, and percentage of occurrence of Es and spread F. A comparison is made between foF2 values scaled from the Bangkok C-2/3/4 sounder and the Granger sounder for two brief periods--6 April through 7 May 1966, and 1 June through 19 June 1967--when both equipments were operated at the same site.
