Method synopsis

High spectral resolution lidar measurement of aerosol backscatter profiles to detect aerosol layer boundaries and depth. Uses Haar Wavelet transform gradient detection to identify significant changes in backscatter corresponding to aerosol layers.

Synthesized from method descriptions across 3 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — The short life of upvalley wind in a high-altitude valley in the Colorado Rocky Mountains (2025), Journal of Geophysical Research: Atmospheres. Implementations in other papers (listed below) may differ.

1. Deploy high spectral resolution lidar
   Operate HSRL at Gothic emitting laser beam at 532 nm wavelength to measure molecular and particulate scattering. Retrieve absolutely calibrated particulate backscatter cross section profiles with 30 second temporal resolution and 30 m vertical resolution up to 60 m AGL. Average profiles over 10-minute intervals and apply gradient detection using Haar Wavelet transform to identify aerosol layer boundaries.
   Quantities: 1 HSRL instrument, 30 second temporal resolution, 30 m vertical resolution, 60 m maximum range, 10 minute averagingDuration: Continuous daytime operation to avoid uncertainty in near-surface overlap regionConditions: Daytime only operation, upper limit 5000 m to minimize noise
   Equipment: High Spectral Resolution Lidar (HSRL)
