The LSA SAF uses satellite observations to offer vital information for agriculture, forestry, land use planning and disaster management. By analysing parameters such as evapotranspiration, fire detection, and land surface temperature, the LSA SAF supports the monitoring and prediction of environmental changes. It aids in improving sustainable land management practices and helps forecast natural hazards like droughts or floods.

Development Phase: September 1999–December 2004
Initial Operations Phase: January 2005–February 2007
Continuous Development and Operations Phase: March 2007–February 2012
Second Continuous Development and Operations Phase: March 2012–February 2017
Third Continuous Development and Operations Phase: March 2017–February 2022

The following satellite data sources are used to generate LSA SAF products:

MSG (SEVIRI)
Metop (AVHRR, ASCAT)
NOAA (AVHRR)

The LSA SAF operational system is fully centralised at IPMA, Portugal, where all products are generated and archived. Users may access products offline, or in near real-time via EUMETCast. Offline requests may be sent to the LSA SAF.

The design of LSA SAF products was initially driven by the needs of the meteorological, particularly NWP, community. There is, however, a growing number of other important areas, including agricultural and forestry applications, land use, and the broader topics of climate and environment monitoring.
