Unlocking the Skies: Exploring Air Quality with ETL’s Portable Ozone Lidar

Industry: The portable ozone lidar developed by the National Oceanic and Atmospheric
Administration/Environmental Technology Laboratory (NOAA/ETL) serves the environmental
monitoring and atmospheric research industries.

Challenge: The challenge was to create a system capable of accurately measuring ozone
and aerosol concentrations in the lower troposphere with vertical profiling from near the surface
up to 3 km for ozone and from the surface to about 10 km for aerosols.

Extraordinary Aspects of the Paper: The paper highlights the advancement of spectral
holeburning (SHB) and spatial-spectral (S2) materials from theoretical concepts to practical
systems. The developed S2 spectrum analyzer (S2 SA) achieved continuous monitoring of a 20
GHz bandwidth, capturing dynamic microwave activities with high sensitivity and resolution. This
system surpasses traditional spectrum analyzers by offering 100% signal detection probability,
avoiding the limitations of narrowband scanning, and demonstrating superior spur-free dynamic
range (SFDR). Additionally, it showcases the potential for real-time direction finding and multi-
emitter tracking, making it a groundbreaking tool in signal processing.
