PO.DAAC Drive provides an FTP alternative for browsing and retrieving data at PO.DAAC. It offers file navigation and download through an interface served directly through your browser, and with a familiar look and feel.
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.

The Mining and Utilizing Dataset Relevancy from Oceanographic Datasets to Improve Data Discovery (MUDROD) is collaborative effort between George Mason University and NASA JPL to improve the search and relevancy ranking of oceanographic data via a simple search interface and powerful backend services. >>
OceanXtremes is a computational platform powered by an intelligent, Cloud-based analytic service backend that enables execution of domain-specific, multi-scale anomaly and feature detection algorithms across the entire archive of ocean science datasets. >>
The Distributed Oceanographic Match-Up Service (DOMS) is a collaborative effort between FSU/COAPS, NCAR, and NASA JPL. DOMS reconciles satellite and in situ datasets in support of NASA’s Earth Science mission. >>
The Virtual Quality Screening Service (VQSS) is a quality-based data filtering and subsetting service. >>
Local instance of Giovanni toolkit for the statistical intercomparison of geophysical parameters using some of our own PO.DAAC datasets. >>
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 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.
- EOSDIS Tools
Earthdata Search application allows you to search, discover, visualize, refine, and access NASA Earth Observation data. It 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)
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).
- Aquarius L3 Image Browser
Images are produced from the validated Version 2.0 Aquarius/SAC-D data.

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.
