Sahai, Y., Bittencourt, J.A., Teixeira, N.R. and Takahashi, H. (1981). Simultaneous observations of OI 7774-Å and [OI] 6300-Å emissions and correlative study with ionospheric parameters. Journal of Geophysical Research 86: doi: 10.1029/JA086iA05p03657. issn: 0148-0227.

Regular measurements of the OI 7774-¿ and [OI> 6300-¿ nightglow emissions were carried out at Cachoeira Paulista (22.7 ¿S, 45.0 ¿W), Brasil, during the period April 1978 to March 1979. An ionosonde is also operated at Cachoeira Paulista. A correlative sutdy of the OI 7774-¿ and [OI> 6300-¿ emission observations, with simultaneous ionosonde measurements, shows good correlations between (J7774)1/2 and F layer peak electron density (nm(e)) and between the ratio (J7774 1/2/(J6300) and the height of the F layer (hmF2), where J7774 and J6300 are the column emission rates for the OI 7774-¿ and [OI> 6300-¿ emissions, respectively. Simultaneous measurements of these two emissions would be a very useful technique for remote sensing of the ionospheric F layer dynamics.
