ionogramn.
/ʌɪˈɒnəɡram/, U.S. /aɪˈɑnəˌɡræm/ 1. Chemistry and Medicine. A record or image produced as the result of an ionographic separation, typically a series of spots or bands on the support medium. Cf. ionography n. 1.

1952 Jrnl. Amer. Chem. Soc. 74 1619/1 The ionogram was dried on a glass plate by a stream of hot air.
1963 Proc. 17th World Vet. Congr. II. 1107 The ionogram of serum represents the electrolytic compounds of extracellular fluid in dogs.
2002 Lancet 28 Sept. 996/1 An arterial blood sample showed normal ionogram, urea nitrogen, creatinine, liver function test..and blood count.
2. Atmospheric Physics. A graphical record of the data transmitted by an ionosonde.The data are typically presented in the form of a plot of virtual height of the ionosphere against transmitted frequency.

1955 Sci. Amer. Sept. 128/2 To make an ionosonde record (ionogram) the transmitter and receiver are tuned rapidly through a range of frequencies. The echoes received are displayed on a cathode ray oscilloscope and photographed.
1963 Times 15 Feb. 7/7 Some 70,000 ‘ionograms’—graphs of frequency against depth of reflection below the satellite—have so far been obtained and are of good quality.
1974 Nature 1 Nov. 26/1 Development of several well stratified ionospheric layers between 100 and 200 km is visible in the ionogram taken at 1000 UT.
2010 Planetary & Space Sci. 58 1391/2 We construct a realistic ionogram of the Martian ionosphere by using..electron density profiles.
