Implementation of observing systems, data management and services in ADRICOSM-EXT Giuseppe M.R. Manzella – ENEA La Spezia – Italy
Vital Contributions • Vanessa Cardin OGS • Vlado Dadic IOF • Franco Reseghetti ENEA • Leda Pecci ENEA • Maurizio Massi TecnoEl • Stefano Nativi CNR • Giovanni Coppini INGV
Content • Meteorological station • XBT and CTD measurements • NRT data management/services • Archiving and data services • THREDDS catalogs and merger
Meteorological station • Adricosm provided the opportunity to add atmospheric data to XBT • Data Logger Campbel Scientific Inc • Thermo Igrometer Rotronic • Weather & Radiation TecnoEl • Barometer TecnoEl • Sonic anemometer WindObserverII
Meteorological station • Only in Summer 2006 the stations were available • GPS recently acquired and delivered • 3 manuals delivered (Campbel, +2 TecnoEl) • OGS and IOF will present results
Operational requirements • Provide repetitive measurements along transects • Transects crossing significant features • Stations distance resolving significant scales • Simple technologies
XBT & CTD measurements XBT and CTD measurements from Oct. 2005 to Nov. 2006 • Adricosm Ext observing system is part of a wider MOON network • MOON provides BC to Adricosm
XBT & CTD: protocols Protocols for Field Work (how, what, if, best practices) QC procedures (IOC, MedAtlas, IAEA/MEL) Calibration and Intercomparison
XBT QC Calibration of XBTs at NURC 4 temperatures (12.5, 16.0, 20.0 and 24.0 °C) XBTs temperature values were larger than reference ones, with maximum differences ranging from 0.04 °C (at 12.5 °C) to 0.08 °C (at 24.0 °C). Comparison with CTD and MedArgo
XBT Data Acquisition Sippican hand launcher LM3, MK12 or MK21 redout card personal computer plastic tube from the hand launcher to (near)the sea surface, to eliminate the wind effect on the XBT copper wire
CTD Data Acquisition Idronaut & SeaBird probes Calibrated Quality assured by experience of groups

Few definitions (1) • Inventory: is an index of distributed data, documentation, and information products relevant to users. Data Inventory may provide hyperlinks to distributed sites where data and metadata are housed (e.g. WWW pages, FTP sites, data repositories, …). • Catalog: describes the entities (e.g., fields or columns in the data base), the quality, the method used, the platforms, and other detailed information for accessing the data. For practical reasons the metadata contained in the catalog are quite limited.
Few definitions (2) • Interoperability: Ability to access, exchange, relate and combine information from multiple heterogeneous sources • Information: knowledge acquired through study or experience or instruction • Data: a representation of information in a form suitable to be automatically managed
Ideal data service (1) • User-friendly interface • Transparency (format, protocol, …) • Capabilities for server-side operations (e.g. subsetting, subsampling, etc) • Aggregation of data and products • Integration across data types, formats, and protocols
Ideal data service (2) • Interoperability across components and services • Flexibility, extensibility, and scalability • Support on array of tools for accessing, processing, management, and visualization • …
Data variety • Simple point or vector data • Grid data as RS • Model output or other hierarchically structured data • Flat files • Binary files • RDMBS
Data storage and convention • Store data in a machine-independent, self-describing format (e.g.) • NetCDF (Network Common Data Form) • HDF (Hierarchical Data Format) • GRIB (Gridded Binary) • Use a ‘standard’ convention (e.g. Climate and Forecast /COARDS)

Data servers • OPeNDAP • ADDE (Abstract Data Distribution Environment) • NetCDF via HTTP protocol In many cases data access systems are augmented and integrated with THREDDS catalog services (inventory list and metadata access)
A layered approach • ’80s microprocessor based computer systems, Internet connectivity, TCP/IP communication standard for data transport TCP/IP 1st layer • ‘90s WWW (interactive services), digital library, open access – open source – open standards interrelated concepts
OPeNDAP/DODS • OPeNDAP (Open source Project for a Network Data Access Protocol) is a preferred platform by DMAC, MERSEA, oceanographic and meteorological communities • DODS and OPeNDAP projects are technically distint efforts. DODS servers are the only ones capable to serve OPeNDAP protocol
The second layer • DODS requests are HTTP GET request. • For gridded data DODS is a ‘good’ candidate. Second layer OPeNDAP HTTP TCP/IP First layer
DODS DODS Data Access Protocols (DAP) servers (some of them) • netCDF • HDF • RDBS (for RDMBS) • FreeForm • COLA GrADS (GRIB, netCDF, HDF,GrADS binary) • Matlab
The third layer • There is ongoing work to enable DODS servers to span files. OPeNDAP aggregation server is (in my opinion) being obsolesced by THREDDS THREDDS OPeNDAP HTTP TCP/IP
Underway efforts • IOOS DMAC efforts • OPENDAP • THREDDS • SOAP/XML • GIS • UNIDATA • THREDDS/OPeNDAP • OGC

Lesson Learned • The SOOP in the Mediterranean is still on a pilot phase. It has been demonstrated that it is working. • For the coastal areas it is important to have very well organised and motivated groups (e.g. Daphne) • The passage to operational system requires some internationa agreements
Lesson Learned • The NRT and Delayed mode data management is qualitatively high • A distributed information service is still at an early stage • Different architectures are under development for different communities • Security issues have to be resolved

Lesson Learned • The success of an operational system is based on a strong collaboration Best thanks to all colleagues
