Search and Order Tools

An on-line, short-term data cache providing a Web interface and FTP access to select ASDC data products. Specially subsetted and/or reformatted data products supporting field campaigns are also available.

The CALIPSO Search and Subsetting web application enables a more sophisticated approach to selecting and ordering CALIPSO lidar data by date, time and geolocation. Data products can be subset by parameter and geolocation including ESDRI-defined regions. Output can be requested in HDF or netCDF.

Earth Explorer (EE) LP DAAC The Earth Explorer (EE) tool provides users the ability to query, search, and order satellite images, aerial photographs, and cartographic products from several sources. EE provides access to MODIS land data products from the NASA Terra and Aqua missions, and ASTER level-1B data products over the U.S. and Territories from the NASA ASTER mission.

A directory to Earth science data, services, and climate diagnostics, the Global Change Master Directory (GCMD) allows users to discover and access more than 25,000 Earth science data sets and services covering all aspects of Earth and environmental sciences. Users can search using controlled keywords, free-text, map/date, or any combination of these. Users can also search or refine a search by data center, location, instrument, platform, project, or temporal/spatial resolution.

A Web-based interactive tool for data discovery and download for all Group for High Resolution Sea Surface Temperature (GHRSST) products. The MMR provides a simple spatial/temporal/product search interface to discover and directly access all GHRSST products, irrespective of their location at the PO.DAAC, NOAA NODC or regional data provider distribution node.

The Hydrologic Data Search, Retrieval, and Order (HyDRO) system allows the user to search data set holdings at GHRC. HyDRO provides a list of GHRC data sets specific to the user’s requirements. Users are able to browse the online information and tools or services for each data set. They can download online data sets by FTP or place an order.

Mercury is a Web-based system for searching metadata and retrieving selected data. Data and documentation can reside anywhere on the Internet, including in a data center or, for a project, on the individual data providers’ servers. Mercury keeps the central metadata current by updating its database every night. Mercury supports international metadata standards and is compatible with Internet search engines.

Online web-based data ordering for MODIS Level 1, Atmospheres, geo metadata and ancilliary products. Capabilities include parameter, geographic, and temporal subsetting, metadata search, masking, channel subsetting, tile and granule reprojection, GeoTIFF reformatting and mosaicing. User friendly services including order tracking, data delivery options (ftp push, pull, direct download) and shopping cart function. Direct access is available at ftp://ladsweb/ for MODIS Level 1, Atmosphere, geo metadata and ancillary products.

The MODIS Interactive Subsetting Tool (MIST) provides subsets of certain Version 5 (V005) MODIS products, over the Greenland Climate Network (GC-Net) and the International Arctic Systems for Observing the Atmosphere (IASOA) stations. Data are provided in a text Comma Separated Value (CSV) file format.

Noesis is a semantic search tool that uses an ontology to guide users to browse the concept space and focus their search term. In addition to being a semantically-enhanced search engine, Noesis is also a resource aggregator collating relevant information from distributed resources. It is an example of Service Oriented Architecture (SOA) leveraging distributed web services for semantic mediation and interaction with other search tools.

OPeNDAP (developed at the University of Rhode Island, P. Cornillon) provides software which makes local data accessible to remote locations regardless of local storage format. OPeNDAP also provides tools for transforming existing applications into OPeNDAP clients (i.e., enabling them to remotely access OPeNDAP served data). Access is provided to select MISR, TES, MOPITT, and CERES data products at the LaRC ASDC, select AIRS, TRMM, GLDAS, TOMS, and OMI data at the GES DISC as well as the following data held at the PO.DAAC- QuikSCAT, GHRSST, TOPEX/POSEIDON, SSM/I, and MODIS SST.

The Next Generation Earth Science Discovery Tool provides a new interface for discovering, accessing, and using EOS data products and services. This web-based client for discovering and ordering cross-discipline data from all twelve of the EOSDIS data centers’ metadata holdings. Reverb allows users, including those without specific knowledge of the data, to search science data holdings, retrieve high-level descriptions of data sets and detailed descriptions of the data inventory, view browse images, and submit orders to the appropriate data providers.

Vertex is ASF’s Data Portal designed to discovery and download data from the ASF Datapool. All SAR products available through the ASF DAAC can be downloaded through Vertex. The interface provides the ability to search for data geographically and by date range. Browse products can be examined and the geographic location of each frame is visible on the map provided.
