Short summary
A near-infrared imaging spectrograph (NIRIS) has been developed in-house and is being operated from a low-latitude location, Gurushikhar, Mount Abu (24.6° N, 72.8° E), in India. The results presented in this study provide us with a comprehensive picture of mesospheric wave dynamics in terms of characterizing their response to various sources (solar and atmospheric) that give rise to the variability in the mesospheric intensities and temperatures.
