GMES Overview

We care for a safer world33

GMES dedicated missions: Sentinels

2013 / 2015

Sentinel 1 – SAR imagingAll weather, day/night applications, interferometry

2014 / 2016

Sentinel 2 – Multi-spectral imagingLand applications: urban, forest, agriculture,.. Continuity of Landsat, SPOT

2014 / 2017

Sentinel 3 – Ocean and global land monitoringWide-swath ocean color, vegetation, sea/land surface temperature, altimetry

2019

Sentinel 4 – Geostationary atmosphericAtmospheric composition monitoring, trans-boundary pollution

2015, 2020

Sentinel 5 / 5P – Low-orbit atmosphericAtmospheric composition monitoring(S5 Precursor launch in 2015)

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

Sentinels 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)

Primary goal of Sentinels is to serve operational GMES needs – BUT they will have enormous benefits for science:

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

support evolution of next generation Sentinels

11

GMES: economic benefits

“Money where it matters – how the EU budget delivers value to you”

EC, MEMO/11/469, Brussels, 29 June 2011

“Over the 2006-2030 period… the benefits from all the GMES services in full use would equal 130 bn€ (2005 e.c.) or around 6.9 bn€ per year”

“The Socio-Economic Benefits of GMES”

ESPI report 39, November 2011

For 1 € spent by the European tax payer on GMES, a public return of 10 € can be expected

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.)
