Atmospheric composition monitoring, trans-
boundary pollution
2019

8. GMES Sentinel Data Policy Principles
FREE and OPEN*
* Joint Data Policy Principles
adopted by ESA in ’09
* free-of-charge licenses
* Some restrictions may
apply (security, technical,
etc.)
EU Regulation in 2012

9. Sentinels for Science
Primary goal of Sentinels is to serve operational GMES
needs – BUT they will have enormous benefits for science:
Sentinel data represent an invaluable resource for the
science community
Sentinel missions will provide continuity and improved
data from ERS/Envisat/Landsat :
Better data for science
Long term data sets of unique value for science
Sentinels perfectly complement dedicated science
missions (e.g. ESA Explorers)
9
10. Science for Sentinels
Sentinel missions have been defined with strong
support of scientists, in addition to operational users
(e.g. MRDs, EC Implementation groups)
Science community is perfectly suited to:
spearhead new GMES services
ensure high quality data streams through
CAL/VAL activities
improve algorithms and models for the retrieval
of more accurate products during operational
phases
combine Sentinels with GCM data
10
support evolution of next generation Sentinels
11. GMES: economic benefits
“Money where it
“Over the 2006-2030 period… the matters – how
the EU budget
benefits from all the GMES services in delivers value to
full use would equal 130 bn€ (2005 you”
e.c.) or around 6.9 bn€ per year” EC,
MEMO/11/469,
Brussels, 29
June 2011
“The Socio-
Economic
For 1 € spent by the European tax Benefits of
payer on GMES, a public return of GMES”
ESPI report 39,
10 € can be expected November 2011

12. Next steps
• GMES EU Funding 2014-2020 – support GMES inside MFF &
at sufficient level
• GSC-3 – prepare third segment of space component
programme for ESA C-MIN 2012/14
• Sentinel data policy - shall be finalised before end 2012
• Sentinel launches – from end 2013 onwards
• Sentinel data – need to prepare arrival of large data
volumes for user community
• Sentinel data – requires major support actions (cal/val,
algo dvpt, access portals, etc.)

PM2.5, which consists of fine particles measuring 2.5 micrometers in diameter or smaller. To provide some perspective, imagine a single strand of hair from your head: The average human hair has a diameter of 70 micrometers. Fine and course particles are a fraction of this size, which allows them to be easily inhaled into our lungs and respiratory tracts. Fine particles (PM2.5) especially are a concern – their very tiny size allows them travel more deeply into our lungs, increasing the potential for health risks.
