Support for a tropical lidar in Latin America



The vertical profile of stratospheric aerosols is a crucial parameter to monitor the effects of volcanic eruptions on climate. These effects include climate change and ozone depletion. Satellites provide the best instruments for producing global coverage for these profiles, but existing and planned satellite missions all have limitations. Ground-based lidar observations are needed for calibration and validation of satellite observations, as well as for filling the gaps when satellite observations are not available.
