MARS Mission
Ensure Internal European Commission technical competence in the field of administration and control of area based aid declarations and rural zones (MARS-PAC project - 1992)
Independent and timely production estimates for the major European crops (MARS-STAT project - 1989)
Adequate warnings on food security for world-wide regions at risk (MARS food-Aid project - 2001)
Application of MSG
Simulated values of the Thermal Flux (outgoing long wave radiation),
emitted Thermal Flux in W/m2 units

Limitations:- real time data access, no problem
- frequency, no problem, MSG very frequent, every 1/4
hour
- resolution, yes, sometimes too rough
and what about the phenological observation?
