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.  It also allows users to access data via a command line so that interactions can be easily scripted.  As a new feature, thanks to the underlying open technologies,  it also enables mounting the remote data to your own local computer, seeing the data as if you had the entire PO.DAAC archive mounted on your own machine.

PO.DAAC Web Services are application programming interfaces (APIs) that can be accessed through standard web protocols.  The W3C defines a Web Service in part as, "A software system designed to support interoperable machine-to-machine interaction over a network," (for the full definition, see http://www.w3.org/TR/ws-arch/#whatis ). The PO.DAAC Web Services use a Representational State Transfer (REST) model with calls issued over a Hypertext Transfer Protocol (HTTP) connection.  On receipt of a request message, our services return the response in either an Extensible Markup Language (XML) structure or, optionally, a JavaScript Object Notation (JSON) format.

The new version 3.2.2 of the PO.DAAC Web Services have been modified to conform to an updated API in the new HiTIDE/L2SS (High-level Tool for Interactive Data Extraction / L2 Subsetting Services).  Also, there are significant changes in the Granule Subset web service.  The Granule Subset web service is now asynchronous, which prevents web timeouts and allows the subsetting of multiple granules in a single request.  A Granule Subset request is submitted, using http POST rather than GET, and a token is returned that can be used in the new Subset Status web service to determine the state of the Granule Subset request.  There is also a new Dataset Variables web service.

SOTO is a suite of tools presented through an interactive, web-based visualization front end. It provides access to a broad range of satellite-derived products and key parameters of interest to the oceanographic community. SOTO facilitates visual exploration and comparative analysis of physical oceanographic data, enabling scientific oceanographic, climate, and related research.

  • To best experience SOTO, we recommend using a recent version of one of the following browsers:  Google Chrome, Mozilla Firefox, or Apple Safari.  (Note that Internet Explorer is not currently supported.)  Additionally, we recommend that prior to first loading the new SOTO, you clear your browser's cache.

High-level Tool for Interactive Data Extraction / L2 Subsetting Services (HiTIDE)  allows users to subset and download popular PO.DAAC level 2 (swath) datasets. Users can search across a wide variety of parameters, such as variables, sensors and platforms, and filter the resulting data based on spatial and temporal boundaries of interest to the user. HiTIDE goes even further, offering instant previews of variable imagery, allowing users to rapidly find data of interest for download and further, rigorous scientific analysis. HiTIDE's user interface is powered by a set of web services that facilitate machine to machine interoperability.

PO.DAAC created a GitHub for hosting all PO.DAAC code. Each record in the inventory was tagged with labels to indicate the language of the script and the functionality. A standard Apache 2.0 license  was also added to the script. Each script was added to PO.DAAC’s GitHub and exposed to code.nasa.gov through a JSON file.
