Integrated Model Data Management S.Hankin ESMF July ‘04 Integrated data management in the ESMF (ESME) Steve Hankin (NOAA/PMEL & IOOS/DMAC) ESMF Team meeting July 2004
2
Integrated Model Data Management S.Hankin ESMF July ‘04 The growing importance of data integration to modelers: We no longer fund “modeling”. Today we fund “climate prediction” or “coastal processes” … the science topics. Modeling is just a component. a program manager (anonymous)
3
Integrated Model Data Management S.Hankin ESMF July ‘04 Model outputs need to be made useful to many classes of users model run project modeling community research community education
4
Integrated Model Data Management S.Hankin ESMF July ‘04 Data and products need to be made more usable for modelers modeling validation assimilation Real time and delayed-modeobservations data products comparison boundary & initial conditions
5
Integrated Model Data Management S.Hankin ESMF July ‘04 An ESME must include a plan for data management. But, how ? Funds are limited …
6
Integrated Model Data Management S.Hankin ESMF July ‘04 Partnership: A community of data managers has formed … GO-ESSP – Global Organization of Earth System Science Portals (http://esportal.gfdl.noaa.gov) Unidata Unidata ESG (NCAR, LLNL) ESG (NCAR, LLNL) OPeNDAP (a.k.a. ‘DODS’) OPeNDAP (a.k.a. ‘DODS’) COLA COLA NOMADS (GFDL, PMEL, NCDC, NCEP) NOMADS (GFDL, PMEL, NCDC, NCEP) NASA/GCMD NASA/GCMD BADC, BODC BADC, BODC WMO WMO …

Integrated Model Data Management S.Hankin ESMF July ‘04 Ocean data systems following similar approaches … National Virtual Ocean Data System (NVODS) National Virtual Ocean Data System (NVODS) US Integrated Ocean Observing System US Integrated Ocean Observing System GODAE (US and International) GODAE (US and International) OCMIP, AOMIP, … OCMIP, AOMIP, …

Integrated Model Data Management S.Hankin ESMF July ‘04 Data portal components: Workflow Data discovery Data discovery Data access/transport Data access/transport On-line browse and comparison On-line browse and comparison (Segue to analysis) (Segue to analysis)
9
Integrated Model Data Management S.Hankin ESMF July ‘04 Data discovery == Metadata + search Mature standards do not exist today. A task for ESMF: define and utilize metadata standards for modelers
10
Integrated Model Data Management S.Hankin ESMF July ‘04 Metadata for modelers Reviewed & “published” (a “standard”) Reviewed & “published” (a “standard”) Structured (XML) Structured (XML) Generated automatically in conjunction with setting up model runs Generated automatically in conjunction with setting up model runs Standardized parameter names (“controlled vocabularies”) Standardized parameter names (“controlled vocabularies”) Hierarchical Hierarchical –components, grids, fields and attributes
11
Integrated Model Data Management S.Hankin ESMF July ‘04 Others are working hard on search: 1. Traditional metadata partners (e.g. GCMD) 2. Semantic Web (Google on steroids) (3 years off?) Data discovery == Metadata + search

13
Integrated Model Data Management S.Hankin ESMF July ‘04 Data transport OPeNDAP (a.k.a. “DODS”) –Network data access –Format-independence –Subsetting –Aggregation (GDS, Unidata) –Compression –Security: Grid-enabled OPeNDAPg
14
OPeNDAP: distributed access to data and semantic metadata
15
Integrated Model Data Management S.Hankin ESMF July ‘04 CF (“climate and forecast”) CF 1.0 is now a “standard” “use” metadata – e.g. units, coords. “use” metadata – e.g. units, coords. curvilinear, hybrid-Z, time-dependent curvilinear, hybrid-Z, time-dependent great applicability beyond modeling, too great applicability beyond modeling, too Discussion question: As the use of the CF standard widens how should the community support it? Not enough to “endorse” it. Need a partnership.

Live Access Server
18
netCDF
19
Integrated Model Data Management S.Hankin ESMF July ‘04 Metadata (XML) contains the “intelligence” Back end applications do the real work OPeNDAP provides remote data access LAS -- an “Information Product Server” Ferret,CDAT or other
21
Information access Uniform data access
22
Integrated Model Data Management S.Hankin ESMF July ‘04 A “home page” Information access Uniform data access Live Access Server home Area 1 Project 1 Exp 1 Exp 2 Project 2 Area 2 Area 3 Project 3 Project 3 Exp 1 Exp 2 Project 4
23
Integrated Model Data Management S.Hankin ESMF July ‘04 The UI talks to LAS through an XML “web service”
24
For example …
25
On-line comparison
27
Example: Average over a lat-long box

31
Integrated Model Data Management S.Hankin ESMF July ‘04 LAS “sisters” share metadata to form a unified (virtual) site. OPeNDAP allows LAS to difference distributed fields. Collaborating groups of modelers
32
v6.2 customizable interfaces
33
Integrated Model Data Management S.Hankin ESMF July ‘04 “Web Service” access to products XML request protocol implemented and documented XML “package” out implemented and documented XML query protocol under development formal SOAP interface under development
34
A wealth of data products are available through the National Virtual Ocean Data System (NVODS)
35
Example: Zebiac model output “live” from IRI/LDEO
39
Access to observations (WODB -- 9 million ocean profiles)
42
configurable constraints
44
Integrated Model Data Management S.Hankin ESMF July ‘04 Query available data sets: Query variables in data set “model_1”: Query space-time domain: Request a subset of data as a file: (“asc” for ASCII format) “Batch” access to products >lasls http://cpu/LAS >lasls http://cpu/LAS model_1 >lasls http://cpu/LAS model_1 sst >lasget -x 20:60 -y 20:60 -t 11-Dec-2000 -f asc http://cpu/LAS model_1 sst

Recommendations for ESMF 1. Define ESMF metadata standard and use it Consider a GCMD modelers’ portal, too Consider a GCMD modelers’ portal, too 2. Endorse partnership with GO-ESSP and the emerging tools Data available through OPeNDAP(g) Data available through OPeNDAP(g) Live Access Servers for on-line collaborations Live Access Servers for on-line collaborations
