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

Table 1

Observed wave characteristics over Kolhapur during the February-March 2010 campaign are shown for each night (first and second rows on each night show principal and residual waves). The best-fitted wave periodicity and wave amplitudes are shown together with the goodness of fit measured as 𝜒² values.
