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 (eohelp@esa.int) 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
