Access to IPY data and other data sources
"Users of IPY data must formally acknowledge data authors
(contributors) and sources. Where possible, this acknowledgment should take
the form of a formal citation, such as when citing a book or journal article.
Journals should require the formal citation of data used in articles they

Although there is no single or comprehensive IPY data system, IPY investigators are
making their data available through a network of existing and specially
funded data centers, repositories, and distribution systems including project
The DADDI (Discovery,
Access, and Delivery of Data for IPY)
is designed to enable the discovery and access of Arctic data
holdings at multiple archives. The DADDI search also
data harvested by the Global Change Master Directory. The DADDI
search system does not replace the GCMD but augments it
by providing a different search and results presentation interface,
including filters and faceted search options. Direct links to data
are included in the DADDI search output where sufficient information
is provided from the data source,

Other systems designed to aid discovery across the broad distributed
IPY network include:
- The Global
Change Master Directory catalog of IPY data.
This catalog is accessible through the
IPY Metadata Portal.
The directory of IPYDIS partners
and services created by
The IPYDIS coordination office.
If you or your organization is
interested in being listed in that directory, please contact
in Google Earth: This layer for Google Earth
allows users to browse information on IPY projects in a 3-D virtual globe.
The Arctic Research Mapping Application
a map-based interface to browse US-funded projects in the Arctic.
IPY projects will be added to this interface.
The Arctic Portal, which provides maps, data
links, and project information for projects under the Arctic Council.
Many organizations around the world are serving data relevant to IPY. The
IPYDIS coordination office is creating a directory of IPYDIS partners and
services. This will be available soon. If you or your organization is interested
in being listed in that directory, please contact
An IPY Operational Data Coordination
office has been established the Norwegian Meteorological Institute led
by ěystein God°y. Contact
for more information.
The European Centre for Medium Range Weather Forecasting (ECMWF) will
provide, for all IPY researchers, a full set of high-resolution model
products for the IPY observing period. The Norwegian Meteorological Institute
is developing a system to access these data. The first version of the
system available this fall will contain a metadatabase and data download
mechanisms (including data subsetting and THREDDS). Later versions will
slowly migrate towards a
WMO Information System
(WIS) solution as this becomes available.
The IPY Ice-Logistics Portal
provides daily detailed ice charts for all regions of the poles. As part
of the broader PolarView site,
it offers sea ice information (charts and forecasts), snow maps, and
glacier and iceberg monitoring data.
The Global Inter-agency IPY Polar Snapshot Year (GIIPSY)
project is defining requirements to obtain spaceborne snapshots of the Polar
Regions during IPY, and is working with the IPY Space Task Group to coordinate
access to satellite remote sensing form many countries. The following are some
- The Australian Antarctic Data Center manages most data associated with Australia's Antarctic science program.
- The National Snow and Ice Data Center (NSDIC)
provides a broad array of data on the world's frozen realms: the snow, ice,
glacier, frozen ground, and climate interactions that make up Earth's cryosphere.
NSIDC's Atlas of the Cryosphere provides a set of base maps of snow, sea ice, glaciers, ice sheets, permafrost, and more.
- PANGAEA, the Publishing Network for
Geoscientific & Environmental Data, is a public digital library for
science aimed at archiving, publishing and distributing georeferenced data
with special emphasis on environmental, marine, and geological basic research.
The SCAR-Marine Biodiversity Information Network
(SCAR-MarBIN) Web portal provides access to a distributed system of
interoperable databases of marine biodiversity information.
The Tasmanian Partnership for Advanced Computing
(TPAC) is the Australian Partnership for Advanced Computing (APAC) expertise
centre for Earth Systems Science. The TPAC Digital Library for Oceans and
Climate brings together the resources and unique data libraries held by several
Australian climate and marine research institutions.
- The World Glacier Monitoring Service actively supports IPY by providing
monitoring standards for glaciers and ice caps, making readily available
the existing data, and compiling, storing and publishing standardized
