Data Access

   PROTOCOLS  


FTP Site
Most of PO.DAAC's data products are accessible via our anonymous FTP server, ftp://podaac-ftp.jpl.nasa.gov/


OPeNDAP (DODS)

 


OPeNDAP
OPeNDAP enables remote data sets to be accessed through familiar data analysis and visualization packages, just as if they resided locally on the user's machine. OPeNDAP handles transport, translation and subsetting of data residing in most Earth science data formats. For a list of PO.DAAC data accessible through OPeNDAP, see PO.DAAC OPeNDAP data. For the complete list of OPeNDAP Datasets, please see the Unidata OPeNDAP Datasets list.

OPeNDAP data are accessible to users through: MATLAB, IDL, Ferret, Live Access Server.

THREDDS
The THREDDS (Thematic Realtime Environmental Distributed Data Services) project is developing middleware to bridge the gap between data providers and data users. The goal is to simplify the discovery and use of scientific data and to allow scientific publications and educational materials to reference scientific data.
 
   VISUALIZATION  

 

Current State of the Ocean
Current State of the Ocean provides near real-time data that gets diplayed on a virtual globe and is annotated to give context descriptions of the ocean's features and events, kml overlays (ice extent, hurricane tracks, clouds). It also provides data layers for Sea Surface Temperature (SST), wind vectors, and ocean color.
   SUBSETTING:  


GCMD


Dataminer
Dataminer is a web tool for searching and subsetting Level 2 (swath) data. It was developed originally by the French agency Ifremer (an upcoming collaboration is in the works), and modified at PO.DAAC. We are hosting a modified version of this tool now in beta form, and will be adding many more datasets.

Images, Subsetting, Plotting - (POET)

The PO.DAAC Ocean ESIP Tool (POET) provides interactive, on-line subsetting and visualization of many of PO.DAAC's data products. Viewing options include: latitude-longitude maps, animations, time series plots, and space-time profiles.

Format options include: GIS (GeoTIFF, ArcGrid), image (GIF, PNG, JPG), scientific (HDF, NetCDF), and raw (binary, ASCII). This graphical user interface was developed by Ocean ESIP (Earth Science Information Partner).

PO.DAAC data currently accessible by POET include:

Sea Surface Temperature:
Level 3: MODIS, NAVOCEANO, AVHRR Pathfinder, MCSST, NCEP/Reynolds, NOAA/GOES

Ocean Surface Topography:
Along Track: Residuals, Significant Wave Height
Level 3: WOCE Residuals

Ocean Vector Winds:
Level 3: QuikSCAT, ADEOS-II, ERS-1, ERS-2, NSCAT
 

   EOSDIS TOOLS:  

WIST

Warehouse Inventory Search Tool - (WIST)
The Warehouse Inventory Search Tool (WIST) is a client for searching and ordering Earth science data from various NASA and affiliated centers. WIST, which was developed by Earth Science Data and Information System (ESDIS), is intended to give the user community an improved search and order interface. The WIST search-and-order tool has the following features:

* Browse capability—Allows a user to explore the list of data sets or granules returned by a search by viewing their temporal coverage, spatial coverage, attributes (metadata), related documents (guide search), and browse images.
* Order function—Allows the user to select data for ordering, choose packaging information, enter ordering information (such as shipping address), and place an order.
* EOS and related search and access tools—Provides links to other search and access resources for EOS and related data.
 

GCMD
 
Global Change Master Directory - (GCMD)
The GCMD holds Earth science data set and service descriptions, such as location of the data or service, associated investigators and other contacts, spatial and temporal coverage, and resolution that provide vital information to help determine whether the data or service meets the user’s needs. Use the GCMD to search for information about data and services; to order EOSDIS data, use search-and-order systems such as the EDG or DAAC-specific systems.
