ALIMA range-corrected photon count profiles and spectral analysis output

The dataset includes a .nc file of range-corrected and background-corrected photon counts measured by ALIMA (Airborne Lidar for Middle Atmosphere research) from six research flights (ST08, ST09, ST10, ST11, ST12, ST14) during the SouthTRAC-GW campaign in September 2019. These corrected photons counts are proportional to the atmospheric density. The data resolution (t, z) is (10s, 100m) but not yet vertically smoothed nor temporally integrated. A vertical smoothing of 900 m and a temporal integration of 1 min is recommended to obtain a sufficient signal-to-noise-ratio.

Furthermore, .nc files containing spectral power density (PSD) for selected legs of each research flight averaged over 10 km altitude ranges based on vertically smoothed and temporally integrated range- and background-corrected photon counts by ALIMA are included.
