    • GLAS/ICESat L2 Global Thin Cloud/Aerosol Optical Depths Data (HDF5) V033

    Metadata Updated: January 22, 2026

    GLAH11 Level-2 thin cloud/aerosol optical depths data contain thin cloud and aerosol optical depths. A thin cloud is one that does not completely attenuate the lidar signal return, which generally corresponds to clouds with optical depths less than about 2.0. Each data granule has an associated browse product.
