Airglow Measurements of Gravity Wave Propagation and Damping over Kolhapur (16.5°N, 74.2°E)

Figure 1

The observed nocturnal variability noted on February 9-10, 2010 in OH (a, b) and O (1S) emission (c, d) intensities. The solid lines in each plot exhibit the best-fit model results. (a, c) show the intensity deviations from the nightly average, normalized to their nightly averages. (a) shows the sample wave-fit results for two other wave modes together with the selected 8.4 hr wave. One may note the presence of principal nocturnal wave (a, c) and residual wave (b, d) in the data.
