GAWSIS GAW Station Information System Jörg Klausen Second GALION Workshop, WMO, Geneva20-23 September 2010
Associated and partner networks Global GAW stations Regional GAW stations Contributing GAW stations GAWSIS Scope • Collect and distribute metadata to facilitate discovery and use of atmosphericdata from GAW stations and partner programmes.
GAWSIS Design Principles • K.I.S.S. (keep it small & simple) • No Flash etc. • No plug-ins • Little Javascript • Involve the user • Public for viewing • Password-protectionfor editing • Machine-to-machinemetadata exchange • Regular updates • Self-maintaining (well …)
GAWSIS Discovery Tools • Simple search • Advanced search • Links to WDCs • GoogleEarth™ port
CSV formatted GAWSIS Main Features • Lists (and maps) of stations • Lists of contacts • Station reports • Site characterization • Measurement program • Meta data for each series • Hyperlinks to data (archive) • Contacts • Bibliographic references • Clearinghouse for 3-letter station codes (incl. GAW IDs)
Interoperability of data centers • Facilitate discovery • Find information regardless of origin • Find everything about a station • Find all sites measuring a given variable • Converge towards international standards • Same vocabularies • Same quality standards • Facilitate network management and development • Increase visibility and traffic to archives
CAPMon Operational & comprehensive Operational, incomplete No direct link at present GAWSIS – Metadata Integration for WIS WDCPC WMO Global Atmosphere WatchWorld Data Centre for Aerosols AERONET
WIS Compliance of GAWSIS Achieved within ET-WDC WIGOS/WIS Pilot Project • Metadata from various sources are exposed as WIS-compliant XML files, ready for harvesting
Data Retrieval – A future capability of GAWSIS? • Example of quicklook plot produced with data retrieved from WDCGG • This capability would be useful if correlative plots with data from different archives could be produced ...
GALION in GAWSIS • GALION stations are identified and discoverable in GAWSIS
Challenges / Future Directions • Maintenance of metadata information • Responsiveness of station managers • Availability of metadata from data centres • Identification of metadata items obtained from data centers (vocabularies!) • Need to decide what stations/programmes to include in GAWSIS and establish trusted relationships with (meta)data providers • Renewal of GAWSIS architecture • Establish GAWSIS as a permanent World Data Centre for Metadata within GAW with a view of becoming a DCPC in WIS (CAS-XV)
Future Plans (~18 months) • Include AERONET, SKYNET if agreements can be found • Improve GAWSIS’ capabilities to use and offer web services • Improve vocabularies • Improve and extend information on data quality • Agree on GAWSIS as clearing-house for Laboratory ID (much like GAW IDs) and implement a scheme • Extend search capabilities in response to user requests
What do I need to do? • Go home and enter your page information • Remember that your site is tentatively a contributing station • We need a step to confirm that sites that submit their information are accepted into the GALION family • Please copy me, Gelsomina, and Geir when it is done
