Comparison of the OH (8-3) and (6-2) band rotational temperature of the mesospheric airglow emissions

The airglow OH (8-3) and (6-2) band rotational temperatures were measured and compared using two scanning photometer at Cachoeira Paulista (23oS, 45oW) in 1999. The rotational temperature were obtained from the ratio between the P1(5) and P1(3) in the case of the (8-3) band and P1(4) and P1(2) lines for the (6-2) band. Three different Einstein coefficients, of Mies (1974), Langhoff et al., (1986) and Turnbull & Lowe (1989) were used and compared between them. It was shown that both the temperature did agree well with in an error range when the Langhoff et al.'s coefficients were used.
