20. Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Provision of Auxiliary data for SNES and LNES LNES need Pressure Water vapour content Ozone content Site BRDF Aerosol SNES need Pressure Water vapour content Ozone content Water leaving radiance Aerosol

21. Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Provision of Auxiliary data for LNES Meteorological data Source Meteorological institutes Land Aerosol : No data Surface BRDF Use Polder database Use SADE Use specific angular conditions

22. Consulting and Technology Technical Excellence | Pragmatic Solutions | Proven Delivery Provision of Auxiliary data for SNES Data available in the climatological database Chlorophyll content estimated from MERIS level 3 products Aerosol model estimated from MERIS level 3 products Meteorological data Pressure, water vapour content and ozone are provided within the satellite data and are issue from Meteorological center (ECMWF, NCEP etc) Level 3 Aerosols Two suggestions have been made in WP 220 to develop a L3 AERONET database AERONET can be used to propose a climatology of the aerosol models (among SAMs). AERONET can be used to build a local climatology of the aerosol inherent optical properties Aerosol from AERONET network Use of L1 AERONET data One suggestion has been made in WP 220. AERONET CIMEL can be used as well in the satellite match ups for: Flagging the situation with too high aerosol turbidity. Selecting a SAMs, through the Angstroem coefficient in the NIR. Using the CIMEL AOTs in the blue. Some potential site candidates have been listed in WP 220.
