2. Purpose and Requirements • Visual inspection of • Mapped Level-2 DDS • Mapped Level-3 PPS, FPS • Binned Level-2 DDS • Binned Level-3 DDS, PPS, FPS • Validation • Match-up of Level 2 DDS OC data with in-situ data • Match-up of Level-2 DDS and Level-3 DDS OC data • Statistical analysis and report of match-up results GlobCOLOUR CDR, 10-11 Jul 2006

3. Status of Development • Release 1.0 • Import of mapped and binned DDS, FPS, PPS products • On-the-fly resampling from ISIN to Plate-Carree • On-the-fly expansion of stored data into mean and variances • Flag-codings and bitmask overlays enabled • Handling of no-data values • Automatic attachment of pins at diagnostic sites • VISAT facilities • JIRA issue tracking • Tracking of bugs and feature requests • Automated generation of release notes • Web interface GlobCOLOUR CDR, 10-11 Jul 2006

5. Open Issues • Release 1.0 • Which technique to use for resampling of ISIN gridded data onto Plate-Carree? • Flag-coding specification incomplete • No-data value undefined • Further planning • Focus on automated analysis of large amounts of data (e.g. time series) instead of visual per-pixel inspection • Identification of use cases concerning match-up and statistical analysis • Review of software requirements in collaboration with the validation team • Consideration of alternative approaches: Is it favourable to implement the match-up processing as a web service?
