Cal/Val activities
Scope and Objectives• The ESA scope is to serve the end user with EO data produced with the
best overall system composed of the flight and ground segment.
• The objective is to meet and exceed the scientific and operational missionrequirements (e.g. Mission Requirement Document). These requirementsare evolving all along the missions with the inputs of the user communities.
• The SPPA (Sensor Performance, Products and Algorithms) activities are:– Product Algorithm Development, Verification and Maintenance
– Instrument Processors (IPF) Development, Verification and Maintenance
– Routine Calibration and Validation• Transponders
• Balloon, Aircrafts and Oceanographic Campaigns
– Data Quality Control
– The support to EO Help ([email protected]) for user technical requests
– The reporting• Mission Documentation (e.g. product hand book)
• Mission Status and evolution (e.g. instrument cyclic and monthly reports)
• Functional reporting (e.g. operation monthly report)

Cal-Val during routine phase
• Scope
– make the best use of the instruments
– tune the processor to produce the best products
– evaluate the opportunity for processor evolution
– assess the need for product evolution
• Strategy
– Continuity with respect to the Commissioning phase setup
– Based on ESL’s and PI’s support
– Re-focused on routine / long term activities
Cal-Val during routine phase
• It is the responsibility of EOP-GQ to propose theoverall Cal/Val activities for the routine phase, to bereviewed in details with EOP-P, EOP-GU and EOP-S. This shall contain the role of the various entities, adetailed plan for the activity transfer
• In order to optimize the transition between theCommissioning phase and the Long term Routinephase (After Launch + 6 toward the end of themission), a transition phase will be put in place.
• This transition phase will depend on the instrumentand on the type of activity.
Objectives
• Monitoring of the data product quality
• Improvement of the data product quality
• Validation of products generated with newAlgorithms
• Report to the User Community about anyimprovements, problems, and any aspects related tothe sensor and the data processing
• Report and submit upgrade proposals to the project
• Collect feed-back from the users
• Ensure that the quality of SMOS data products ismaintained all along the mission
Algorithm Evolution
• Monitoring of scientific analysis of Cal/Val PI’s with thesupport of EOP-GU (PI’s coordination) and EOP-S (ScienceDivision)
• Conversion of the results of this monitoring activity intorequirements for processor upgrade or the development of newgeneration of processors
• Algorithm upgrade or new development by the Expert SupportLaboratories (ESL’s), Algorithm Validation
• Upgrade or new development of the Instrument ProcessingFacilities (IPF’s)
• Qualification and installation of the new processor in theEnvisat Ground Segment
• Data reprocessing when required
Industrial Support
• Platform and Instruments– Responsibility of the Post Launch Support Office (EOP-P)
• Overall PDS– Responsibility of the EOP-G
• Instrument Processing Facilities (IPF’s) maintenance– Responsibility of EOP-GQ
• Product Quality Tools maintenance (MF, SMOS DataViewer, IAT’s, …etc…)– This is the direct responsibility of EOP-GQ, once delivered
• The Product Handbook maintenance become theresponsibility of EOP-GQ to guaranty the perfectmatching between the current version of the IPF’sand the DDT
