    Aeolus L2A Aerosol/Cloud optical product

    The Level 2A aerosol/cloud optical products of the Aeolus mission include: Geo-located consolidated backscatter and extinction profiles Backscatter-to-extinction coefficient LIDAR ratio, scene classification Heterogeneity index Attenuated backscatter signals. Resolution: Horizontal resolution of L2A optical properties at observation scale (~87 km); Exceptions are group properties (horizontal accumulation of measurements from ~3 km to ~87 km) and attenuated backscatters (~3 km). Note: The resolution of "groups" in the L2A can only go down to 5 measurements at the moment, i.e. ~15 km horizontal resolution. This could be configured to go to 1 measurement - Vertical resolution 250-2000 m (Defined by Range Bin Settings).

    Aeolus Level 2C assisted wind fields resulting from NWP (Numerical Weather Prediction) assimilation processing

    The Level 2C wind product of the Aeolus mission provides ECMWF analysis horizontal wind vectors at the geolocations of assimilated L2B HLOS wind components. The L2C can therefore be described as an Aeolus-assisted horizontal wind vector product. The L2C is a distinct product, however the L2C and L2B share a common Earth Explorer file template, with the L2C being a superset of the L2B. The L2C consists of extra datasets appended to the L2B product with information which are relevant to the data assimilation of the L2B winds.

    Aeolus preliminary HLOS (horizontal line-of-sight) wind observations for Rayleigh and Mie receivers

    The Level 1B wind product of the Aeolus mission contains the preliminary HLOS (horizontal line-of-sight) wind observations for Rayleigh and Mie receivers, which are generated in Near Real Time. Standard atmospheric correction (Rayleigh channel), receiver response and bias correction is applied. The product is generated within 3 hours after data acquisition.
