Conclusions ESA EO data policy 9 ESA has a single EO data policy for all its own missions (Envisat, ERS, Earth Explorers) and its Third Party missions. ¾ during the GMES pre-operations period, the GMES data access will be governed by specific Terms & Conditions. 9 The data policy for the Sentinel satellites is to be defined. 1.

Conclusions EO data products at ESA 9 ESA usually provides data products to users up to Level 2 (CEOS definition). ¾ In some cases (user community requirements), additional product levels are provided: e.g. demonstration Level 3 products, Orthorectified Level 1 products. 9 When relevant, same processing algorithm/format are used between missions (e.g. ERS and Envisat). 9 Product calibration and validation are important activities to ensure products acceptance by user communities: ¾ Missions cross-calibration and cross-validation is essential for users ¾ ESA support for calibration and validation for Third Party missions when requested Product generation modes Systematic:Systematic: •• Products Products areare generatedgenerated automaticautomaticallyally forfor allall receivedreceived rawraw datadata OnOn Request:Request: •• Products Products areare notnot generatedgenerated unlessunless spspecificallyecifically requesrequestedted byby anan useruser NearNear RealReal TimeTime (NRT):(NRT): •• Products Products generatedgenerated withinwithin 33 hourshours fromfrom sensingsensing Off-LineOff-Line (continuity(continuity ofof servicesservices fromfrom NRTNRT toto Off-Line):Off-Line): •• Products Products generatedgenerated aa fewfew dadaysys toto weeksweeks fromfrom sensing;sensing; •• Similar Similar toto NRTNRT productsproducts (same(same format,format, samesame processingprocessing algorithmsalgorithms wheneverwhenever possible);possible); •• Benefit Benefit fromfrom anan improvedimproved knowledgeknowledge ofof auxiliaryauxiliary datadata (e.g.(e.g. orbit,orbit, calibration);calibration); •• Reprocessing: Reprocessing: whenwhen aa newnew procprocessingessing algorithmalgorithm isis availableavailable UnconsolidatedUnconsolidated product:product: •• Product Product generatedgenerated inin NRTNRT usingusing availableavailable auxiliaryauxiliary datadata (i.e.(i.e. maymay nonott bebe mostmost preciseprecise orbitorbit vectorsvectors oror calibrationcalibration information).information).
