Status ESAC Site • OPS-1 ready; subsystem installation underway; furniture for early 2007 • Network installation underway; external access at end of 2006 PLPC-PXMF/SPGF • Accepted at ESAC in October; ready for GSOV XBAS • Front end processing system from SMP very late; acceptance expected in November • Antenna ready at Indra; Demeter tracking before year’s end; acceptance at ESAC expected in February • FEP-AIT to be delivered to CASA in November for first SMOS space-toground compatibility testing • Analysis shows that for full polarisation descending (evening) passes at ESAC are not sufficient for X-band download; some ascending (morning) passes will need to be used SMOS SAG, November 2 -3, 2006

SPQC SW system that operationally controls the quality of all SMOS products and auxiliary data before they are released to their final users April 06 KO July 06 Nov. 06 FAT V 1 CDR ESA detailed specification of checks Mar. 07 FAT V 2 DPGS V 1 LTA and DPGS V 2 Example checks resulting in no wide distribution to users: • File internal consistency: size, structure, coherence • Product confidence data generated by processor is bad • Too many unrealistic values in product • Product cannot be processed to next level SMOS SAG, November 2 -3, 2006
MF SW system that 1) monitors performance of instrument, platform, and ground segment, and 2) performs automated data synthesis to help with calibration and product quality assessment ESA detailed specifications April 06 July 06 Nov. 06 Mar. 07 KO CDR FAT V 0 July 07 FAT V 1 Dec. 07 FAT V 3 FAT V 2 DPGS V 1 and LTA DPGS V 2 Example reports: • • Daily monitoring of on-board temperatures Daily monitoring of DPGS production versus planning Monitor aux data usage Monitor temporal and spatial distribution of anomalous values Continuous collection of statistics per pixel Monitoring of SMOS product values versus external sources Monitor archiving and distribution completeness SMOS SAG, November 2 -3, 2006
SMOS Data Viewer For all SMOS products and auxiliary data, the SDV 1) aids in the viewing of the contents, and 2) provides specific visualisation functions to help in the detailed analysis of the contents Mar. 06 June 06 Oct. 06 Feb. 07 KO CDR FAT V 1 FAT V 2 L 1 A, L 1 B only L 1 C, L 2 added Generic visualisation (scatter plot, temporal plot, spectrum plots, histograms) Specific visualisation: • L 1 A: Correlator matrix (I, Q, amplitude and phase) for science and calibration products • L 1 B: Visibilities in the star domain • L 1 B: Fourier transformation of BT components in the star domain June 07 FAT V 3 Specific visualisation: • L 2: TBD • L 1 C: Projection on to a map (selection of incidence angle range) The SDV V 1 version will be made available to all, along with a set of sample products, in early December.

XML R/W API Test Data File Formats XML Read/Write API • XML schema (Bin. X language for binary data sets) • subsystem/system acceptance • algorithm verification/validation • documents L 0 Processor MF SPQC Aux. Data Handling L 1 Processor L 2 Open Processor Prototype A first coherent set (XML R/W API, schemas, test data) will be available to all in December up to L 1 C. Level 2 should be available by March. All of these tools will evolve with the processor developments throughout 2007. SMOS SAG, November 2 -3, 2006
Data Distribution Time Critical User Nominal User Eoli Interface (eoli. esa. int) • internet browser based ordering (L 1 B, L 1 C, L 2 user, SMOS ECMWF only) of small volumes (<50 products) • intended for users new to SMOS • subscription configuration • on-call support during working hours Data Dissemination ESAC User Services Help Desk New User • all fast processing files • time critical users via network, everyone else via media • subscriptions: time range, geographic area, ascending/descending • likely >> 10 Mbps for SMOS ESRANGE • all fast processing and reprocessing files • time critical users via network, everyone else via media • subscriptions: time range, geographic area, ascending/descending • likely >> 50 Mbps for SMOS SAG, November 2 -3, 2006
Coming Attractions ECMWF Data Assimilation Study • Prepare for the operational assimilation of SMOS data with a goal to reduce the start-up time • Provide inputs to aid in SMOS validation activities • KO by January with a 27 month duration Surface TB Processor • On-going project with CLS will deliver an ATBD for spring 2007 • This project takes the ATBD and produces an operational processor that will go in the CEC at launch and in the operational fast processing chain by the end of commissioning • Open ITT to go out in early 2007 with a KO by May SMOS SAG, November 2 -3, 2006
Coming Attractions Reprocessing Study • Current processor implementation addresses only the fast processing scenario and not a reprocessing campaign: no allowance for improved aux. data or calibration processing • Take current L 1 and L 2 DPMs and modify these to apply to the case of a reprocessing campaign • Open ITT to go out in early 2007 with a KO by May and a completion at the end of 2007 • There will be a follow-on activity to implement this DPM in the Reprocessing Centre of the LTA for the first reprocessing campaign (expected to follow shortly after the end of the commissioning phase) SMOS SAG, November 2 -3, 2006
Coming Attractions NRT Service • Decision will be made at the next PB-EO (November 23 -24) • Proposal is to acquire during each of the 10 non-ESAC orbits and deliver the data (one file per APID) to ESAC for processing using a separate NRT processing chain and then distribution to NRT users via the baseline ESAC data distribution infrastructure • Procurement will be by two open ITTs: 1) acquisition of the 10 non. ESAC orbits and delivery to ESAC, and 2) implementation of a NRT processing chain largely independent of the existing DPGS infrastructure • Not the optimal solution financially or technically but meets all the political constraints for acceptance SMOS SAG, November 2 -3, 2006
Summary • It is subsystem acceptance and integration season and this will likely continue for the next four-six months • The Fast Processing and LTA developments are both experiencing delays but this is no longer launch critical; a decision will have to be made in summer regarding which system is more likely to be ready and stable at launch • Level 2 operational processor non-start is the biggest fire today • CEC is starting to take shape; although granted it is yet to be visible outside ESA • By next SAG there should be more to show you then these slides and some empty offices at ESAC SMOS SAG, November 2 -3, 2006
