The FIREX-AQ field campaign, led by NOAA and NASA, aims to investigate the impact on air quality and climate from wildfires and agricultural fires in the United States by looking at the chemistry and transport of smoke. Atmospheric Remote Sensing group at NOAA Earth Systems Research Laboratory – Chemical Sciences Division developed a micro-pulsed coherent Doppler lidar system that will be deployed on a Twin Otter aircraft with the goal of profiling wind dynamics of large forest-burning wildfires.This research will be validating airborne wind lidar measurements by comparing wind lidar measurements from a custom-made scanning micro Doppler lidar system deployed on a Twin Otter aircraft to those from different commercial wind lidar systems deployed at three different locations on the ground. This reseach will test if vertical wind variability is the main cause of error on the horizontal wind measurement retrievals.
