Depolarization and Backscatter Unattended Lidar (DABUL)

DABUL operates automatically from its own weatherproof housing, with remote control and data download through a communications link.

NOAA/ETL and the University of Maryland - Baltimore County's Physics Department are collaborating to develop and deploy a long-term, unattended infrared spectroradiometer and lidar to monitor and study the radiative effects of water vapor, aerosols, and thin clouds in the upper troposphere. The infrared spectro-radiometer will measure atmospheric emitted spectral radiance over the wavelength range of about 3-23 micrometers, while the lidar will detect clouds and aerosol layers.
