European Space Agency - ESA
ESA is an intergovernmental
organisation with 19 Member States
ESA purpose:“…provide for and to
promote, for exclusively peaceful
purposes, cooperation among
European States in space
research and technology and
their space applications ....”
Article II of the ESA convention
ESA achieves this through:
• Space activities and programmes
• Implementing a long term space policy
• A specific industrial policy
• Coordinating European with national space
programmes

ESA Satellite Missions & Agriculture
1991 (2000) ERS-1 & 1995 (2011) ERS-2
SAR - Rice mapping, flood mapping, forestry
ATSR - Land surface temperature, vegetation fires, visible surface
reflectances, NDVI, etc
Scatterometer - Soil Moisture (...continuity with SMOS launched in 2009)
2002 Envisat
MERIS added Visible Surface Reflectances, NDVI, Fapar (300m & 1 km)
