  1. SOLAS and the British Atmospheric Data Centre Charles Kilburn Anne De Rudder

  2. BADC Role in UK SOLAS • UK Natural Environment Research Council (NERC) is funding agency • Requirement to lodge data for long-term curation and re-use by community • BODC is the lead data centre • BADC involved in 5 of the UK SOLAS projects • Support data providers with formatting and submission • Support on atmospheric model datasets to archive • Support users with data access according to protocol • Access to third party datasets, often UK Met Office and European Centre

  3. Formats • NetCDF • Climate and Forecasting Metadata Conventions • Half of BADC works on developments for discovery, subsetting and auto-plotting which depends on this standard of archived data • Second format for Excel users is NASA-Ames which is ASCII with a set header of metadata essentials. • Data providers have to do the formatting so this is the key issue towards which we direct the most support

  4. Data ingestion • Fixed filename structure of instrument-location-time • Web-based uploading facility with auto-checking of filenames and formats • Alternatively ftp uploading • Each data production tool, observation station and period of deployment is manually entered in the catalogue with as much supporting information as possible

  5. Data quality • File-based archive • Check for truncated files due to bad transfers • Check for metadata standards in file • Check filename conforms to standard and agreed instrument names and locations • No other quality control – the data could be nonsense

  6. Data dissemination • UK SOLAS web page and project sub-pages for project specific information. • Links to BODC, docs, format details. • Two methods to get data out – web archive browser or ftp. • Can only release data after 1 year to UK SOLAS and after 2 years to everyone • Users agree to access conditions • Non-commercial access only • Joint authorship rule within three years of lodging.

  7. Data products • Cape Verde Observatory data comes in within about 1 month of collection • Also have the Cape Verde trajectory data • DODO project aircraft campaign data • Expect atmospheric model data and more ground-based instrument data
