Short summary
We have developed a user-friendly program that can efficiently deal with extensive amounts of airglow data. We have applied this new program to airglow data obtained at different latitudes in polar, midlatitude, and equatorial regions and demonstrated distinct differences in atmospheric gravity wave (AGW) propagation characteristics and energy distribution. We aim to encourage other AGW research groups to use the program and do comparisons to reveal AGW characteristics on a more global scale.
