In the SWAILS+ project the Aeolus lidar surface returns are used in combination with collocated wind speed observations to retrieve the aerosol optical depth. The retrieval algorithm under development, LARISSA (Lidar Aerosol Retrieval based on Information from Surface Signal of Aeolus), will complement the standard Aeolus (L2) aerosol profile products. Not only as LARISSA provides an opportunity to evaluate the standard Aeolus aerosol products but also since the L2a profile approach lacks sensitivity in low aerosol loading regions where an integrated column approach may be more successful.
In addition, for low aerosol optical depth conditions, it is investigated whether it is feasible to retrieve the:
The LARISSA products are developed at the Royal Institute of Meteorological Sciences (KNMI) in the SWAILS (NSO) and SWAILS+ (ESA) projects.
The resulting aerosol product from LARISSA will be beneficial for various scientific applications including
