- Protocols
PO.DAAC's data products are accessible via our anonymous FTP server, ftp://podaac-ftp.jpl.nasa.gov
OPeNDAP handles transport, translation and subsetting of data residing in most Earth science data formats.
The THREDDS Data Server is a web server that provides metadata and data access for scientific datasets, using a variety of remote data access protocols.
PO.DAAC Web Services are APIs that can be accessed through standard web protocols. They use a ReST model with calls issued over a HTTP connection. On receipt of a request message, our services return the response in either an XML structure or, optionally, a JSON format. - Subsetting
The High-level Tool for Interactive Data Extraction (HiTIDE) is a web-based interface facilitating the search, imaging, and extraction of select Level 2 "swath" datasets from PO.DAAC's archive.
The Live Access Server (LAS) enables the web user to: visualize data withon-the-fly graphics; request custom subsets of variables in a choice of file formats; access background reference material about the data (metadata); compare (difference) variables from distributed locations.
- PO.DAAC Labs
Webification (W10n) is ReSTful Webservice technology providing simplified access to PODAAC data and metadata via HTTP/HTTPS protocols with URLs comprised of well-defined parameters. >> 
Datacasting is an RSS-based technology for accessing Earth Science information. With Datacasting, data providers can reach untold numbers of users using standards compliant PO.DAAC Datacasting Feeds technology. >>
The NASA's Coastal Marine Discovery Service leverages open source technology for unifying coastal ocean data search and discovery with further extension of data visualization, interrogation and query using the web-based Environmental Analysis System (EASy) GIS framework. >>
- PO.DAAC UAT
State of the Ocean (SOTO) Beta Version 4.0 is an interactive, web-based tool to generate informative maps, animations, and plots that communicate and promote the discovery and analysis of the State Of The Ocean (SOTO). It provides a mirror to reflect what the data is capturing, and present what the data is telling us, helping to uncover valuable information that is otherwise not obvious or easy to grasp.
The Metadata Compliance Checker (MCC) is an online tool and web service designed to check and validate the contents of netCDF and HDF granules for the Climate and Forecast (CF) and Attribute Convention for Dataset Discovery (ACDD) metadata conventions. It produces quantitative scoring for these convention attributes as HTML, PDF or JSON outputs.
PO.DAAC Drive is a new way of browsing data at PO.DAAC. Drive is an FTP alternative that allows users to access data via browser and command line as has been traditionally done, but can also allow users to mount the remote data to your own computer, seeing the data as if you had the entire PO.DAAC archive mounted on your own machine!
- EOSDIS Tools
NASA's next generation metadata and service discovery tool, which provides search and access capabilities for dataset holdings at all of the Distributed Active Archive Centers (DAACs) as well as the PO.DAAC.
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.
- SOTO (State of the Ocean)
SOTO 2D provides near real-time data layers (vector and image) that are visualized in an HTML5 interface utilizing open-source tools. SOTO 2D data layers are annotated to give contextual descriptions of the ocean's features and events, and kml overlays (ice extent, hurricane tracks, clouds).
- Aquarius L3 Image Browser
Images are produced from the validated Version 2.0 Aquarius/SAC-D data.

- Dataset Search Help
Need help in searching for a dataset?The keyword search capability on the PO.DAAC Web Portal supports a ”Google-like" query syntax NOTE: that keyword search is NOT case sensitive; a search for "sea surface temperature" will return the same results as a search for "Sea Surface Temperature". More >>
Include a white space between the words to search for pages that may have just one of several words,
Example: Search for GHRSST L4 will return datasets that have keywords GHRSST or L4Wildcard (*) will search for partial text so you do not have to type the full word.
Example: Search for GHRS* will return datasets that have keywords GHRSSTAdd a plus (+) before a word to include all results that include that word.
Example: Search for +GHRSST +L4 will return datasets that have keywords GHRSST and L4Add a dash (-) before a word to exclude all results that include that word.
Example: Search for GHRSST -L4 will return datasets that have keywords GHRSST but not L4
Use quotes to search for an exact word or set of words.
Example: Search for "sea surface temperature" will return datasets that have keyword phrase "sea surface temperature"Plural matching
Example: Search for temperatures will return datasets that have keywords temperature or temperaturesYou can combine any of the above query syntax.
Example: Search for +GHRSST +GOES* will return datasets that have keywords GHRSST and any of the GOES missions (GOES-11, 12, 13, 15). - Data CitationData Citations and Acknowledgments.
NASA data are freely accessible; however, when you publish these data or works based on the data, we request that you cite the datasets within the text of the publication and include a reference to them in your reference list.
A recommended citation is provided for each dataset and appears on the PO.DAAC webpage that describes the dataset. The elements contained in the recommended citation can be reorganized for compliance with a particular reference style that is specified by a publisher.

New PO.DAAC Ocean Story, "Record Texas Flooding Left a “Horseshoe” in the Gulf of Mexico"
SMAP SSS revealed a unique "horseshoe" pattern in the Gulf of Mexico in 2015. This signature was the result of a freshwater plume from the Texas flood, Mississippi River plume, and an unusually strong Loop Current and its anticyclonic eddy.
