Welcome to the ECHO Community
The NASA-developed Earth Observing System (EOS) Clearinghouse (ECHO) is a spatial and temporal metadata registry
that enables the science community to more easily use and exchange NASA's data and services. Currently, ECHO
contains metadata for over 2,200 data collections comprising 73 million individual data granules and 25 million
browse images. ECHO stores metadata from a variety of science disciplines and domains, including Climate
Variability and Change, Carbon Cycle and Ecosystems, Earth Surface and Interior, Atmospheric Composition,
Weather, and Water and Energy Cycle. ECHO also has a services registry for community-developed search services
and data services.
NASA's Earth science data has already proven itself to be extremely useful in understanding the planet Earth as an
integrated system. For example, NASA's EOS data are helping scientists gain a better understanding of the processes
that affect the composition of the ozone and the effects of the composition on climate change. NASA's EOS data is
also helping scientists move forward in their efforts to predict natural occurrences, such as wildfires. The data
used in these studies are archived in distributed locations around the country and archived using different metadata
models for each of the different science discipline communities. To help science communities that need data from
multiple organizations and multiple disciplines, ECHO provides a uniform view of NASA's data. It allows users to
more efficiently search and access data and services and increases the potential for interoperability with new
tools and services. The value of these resources increases as the potential to exchange and interoperate increases.
While ECHO's main objective is to enable broader use of NASA's data, ECHO has been working with other organizations
to provide their Earth science metadata alongside NASA's for users to search and access as well.

Recent Events
August 2008
Landsat Phases II and III Operational
The USGS_EROS (Landsat) provider, made available the Landsat 7 L0Rp, L1G,
and Standard Level 1 Precision Terrain-corrected data in the ECHO Operational system.
19 August 2008
NSIDC EDG Valids Removed
All EDG Valids were removed making ECHO/WIST the primary search tool for accessing
the NSIDC ECS holdings.
25 June 2008
EDG to WIST Transition Begins
All instances of the EDG were patched and users were notified that the
process of transitioning users from the EDG interface to WIST has begun.
Users will begin migrating via EDG and WIST through the remainder of this
year as the EDG data partners remove their valids from EDG.
May 2008
ESA-ECHO Client Released
The European Space Agency (ESA) released its latest client which allows access into the
ECHO holdings. The new EOLI Web Client provides access to ESA catalogues of EO products
via a standard web browser, as well as to the catalogues of other data providers
(for example DLR and NASA ECHO) and is part of ESA's eoPortal.
