Doppler Aerosol Wind Lidar (DAWN) Instrument

Researchers Anna Noe and Eric Altman check out the Doppler Aerosol Wind Lidar (DAWN), an airborne instrument that uses pulsed lasers to detect the movement of atmospheric aerosols such as dust or sea salt. In detecting those movements, it can profile wind vector â€” both speed and direction. Researchers are testing DAWNs capabilities during flights over the eastern Pacific.
