Abstract :
The Geoscience Laser Altimeter System (GLAS) launched in 2003 has provided the first global aerosol profiling from space. GLAS is a two wavelength nadir viewing instrument. The measurement requirement to profile all radiatively significant aerosol layers has been exceeded. Data processing algorithms have provided aerosol scattering cross section profiles, boundary detection and height for all aerosol layers, aerosol optical depth and extinction cross section for data from 2003. The data products are openly available to the global science community.
