Slide 1 Hilfe2 Diese Folie enthält zwei Mastergruppen (Master und Titelmaster), welche den Corporate Design konformen Auftritt definieren. Der jetzt zugewiesene Empa Master 1 sieht für die Titelfolie das Empa Logo vor. Den weiteren Folien ist kein Logo zugewiesen. Für längere Vorträge mit Zwischentiteln empfehlen wir, den Folien mit Zwischentiteln den Empa Master 2 (mit Logo unten rechts) zuzuweisen. Dazu öffnen Sie via Ansicht > Aufgabenbereich > Foliendesign Entwurfsvorlage rechts die Masterauswahl. Nun markieren Sie im linken Ansichtsfenster die Folien, denen Empa Master 2 zugewiesen werden soll (mindestens zwei, ansonsten für den ganzen Satz Empa Master 1 verwendet wird). Weitere Hilfe erhalten Sie bei Monika Ernst, 4995 (Empa, Dübendorf) M. Ernst, 2/4/2005
Outline Introduction The GAW WDC landscape during the first 20 years of GAW GAWSIS Evolution GAWSIS Design elements Interface to users GAWSIS powered by the WDCs (m2m) Interoperability of data centers My definition How GAWSIS can help Achievements Outlook WIS An opportunity for GAW data management ISO compliance of metadata Facilitating access to GAW data The GAW WDC landscape 5 years from now Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 2

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 Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 13

Interoperability: The WMO Information System An evolution from the Global Telecommunications System Current centres NMHSs RSMC RTH WMC Others WIS Centres NC DCPC GISC adapted from: Eliot Christian echristian@wmo.int; 10 June 2008 at the "Ad hoc Information and Advisory Meeting on the Region VI VGISC DCPC project (EUMETSAT, Darmstadt) Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 15

Conclusions Integration of information across all variables Search facility across all variables Clearing house for identification of GAW stations Direct link to data across WDCs (not yet for all) Increased visibility of GAW and partner programmes 1 stop shop for information about the ground based GAW network(s) Listed in GOSIC, GCMD, even acronymfinder.com ; ) GAWSIS defines the GAW ground based observational network GAWSIS could be a precursor for a GAW data portal Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 17
Outlook My Vision I see strong GAW WDCs as the core set of archives, serving a growing user base with growing demands I see other data centers that are relevant to GAW strong enough to co exist serving special communities I see an increasing demand for user friendly access to specialized information lost in a plethora of Google hits I see a WMO Information System that needs standardized access to metadata I see a need for GAW to reach out, yet maintain an identity of its own I see GAWSIS serving this future Description of sites, measurement programs, contacts Co location of sites, clearing house for IDs Cross referencing of observed variables Interface to WIS One way of discovering and accessing data Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 18

GAWSIS Open Issues Status of EMEP, NADP, EANET vis a vis GAW(SIS) to what extent should these networks be included? If they are contributing networks, they should be included! Situation for some large countries (USA, Russia, Canada, UK, Germany ) unclear Identification with GAW generally relatively weak Multiple agencies involved GAW country contact not very reponsive / active No one feels responsible for entire country Decisions, support by Secretariat / JSC needed Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 23
