LSA SAF in a nutshellLSA SAF in a nutshellLSA SAF in a nutshellLSA SAF in a nutshell• EUMETSAT Satellite Applications Facility on Land Surface Analysis:
Dedicated to algorithm development, validation and operational production of land surface related products (primarily) based on European meteorological satellites (MSG and METOP)

LSA SAF Strategy for CDOP-2
• Maintenance, quality monitoring & validation of MSG & EPS inherited products
• Upgrade of existing algorithms for MTG data
Product & Service Continuation
• Overcome known deficiencies of current products• Address requests from user community
New Algorithms / Products aim to:
- Land surface modelling (carbon fluxes, hydrology)
- Agriculture and forest applications
- NWP
- Climate studies
- Environmental monitoring
- Food security15-17 Nov 2010 4th LSA SAF User Workshop, Toulouse, France

LSA SAF products and MTGLSA SAF products and MTGLSA SAF products and MTGLSA SAF products and MTG
• LSA SAF will use radiances from the (Full Disk) Imagery Mission,(SEVIRI follow-up)
• Better spatial resolution will be of benefit to all LSA SAF products• Enhanced spectral characteristics vs. SEVIRI
– FD-VIS 0.4 Better aerosol, should improve AL, SW flux, but also LW flux and LST
– FD-IR 3.8/8.5 Extended dynamical range for fire applications– FD-IR 1.3 et al Improved cloud mask and cloud type specification
• Impact on products– All products, given better clouds– Fire products– AL, radiative fluxes and LST, cascading into other products (VEGA, ET)– More competitive VEGA products with enhanced spatial resolution

Summary, conclusions and perspectives
• Aalgorithm development, validationand operational production of land surface related products from remote sensing data, with a particular emphasis on EUMETSAT satellites:
– LAND– LAND-ATMOSPHERE Interactions– Land Biosphere Applications
• Outlook– Strenghten our links with users, emphasis on collaborative efforts with key users,
including targeted training efforts– CDOP-2 and plans for the upcoming MTG products– LSA SAF partners will participate in GMES land (geoland2)
• Product dissemination– Daily from our web site (http://landsaf.meteo.pt)
– EUMETCAST• Further information
