2 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

3 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

4 Outline Introduction GAWSIS Interoperability of data centers Outlook GAW2009, 5 7 May 2009, WMO, Geneva 3

5 GAW WDC Landscape WOUDC Total/Profile Ozone, UV WRDC (Broadband) Solar Radiation WDCGG Gases (incl. surface O 3 ) WDCA Aerosols WDCPC Precipitation Chemistry WDC RSAT Satellite Remote Sensing GAWSIS Metadata and data access Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 4

6 GAWSIS Evolution Desktop application 22 global 258 regional (103 in WMO RA VI) 2 contributing, 14 associated Web based application 24 global 641 regional (237 in RA VI) 24 contributing Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 5

7 GAWSIS Scope Global GAW stations Regional GAW stations Associated and partner networks Contributing GAW stations GAW2009, 5 7 May 2009, WMO, Geneva 6

8 GAW Stations by Operating Status full operation intermittent operation closed unknown Global Regional Contributing filled symbols: fully operational Joerg.klausen@empa.ch, GAW2009, 5 7 May 2009, WMO, Geneva 7

10 GAWSIS Main Features Lists 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 GAW IDs (3 letter codes) CSV formatted GAW2009, 5 7 May 2009, WMO, Geneva 9

11 GAWSIS Discovery Tools Simple search Advanced search Links to WDCs GoogleEarth port GAW2009, 5 7 May 2009, WMO, Geneva 10

12 New Features of GAWSIS GAW2009, 5 7 May 2009, WMO, Geneva 11

13 New Features of GAWSIS GAW2009, 5 7 May 2009, WMO, Geneva 12

14 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

15 GAWSIS powered by (W)DCs WDCPC CAPMon AERONET Operational & comprehensive Operational but incomplete No link at present Under negotiation GAW2009, 5 7 May 2009, WMO, Geneva 14

16 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 10 June 2008 at the "Ad hoc Information and Advisory Meeting on the Region VI VGISC DCPC project (EUMETSAT, Darmstadt) GAW2009, 5 7 May 2009, WMO, Geneva 15

17 GAWSIS linking the (W)DCs with WIS Services Oriented Architecture Concepts Applied to Specific WMO Systems, draft 23 Jan 2007) GAW2009, 5 7 May 2009, WMO, Geneva 16

18 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

19 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

24 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
