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
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 (SOTO)
Current State of the Ocean (SOTO)
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
PO.DAAC HITIDE Subsetter

PO.DAAC HITIDE (Subsetter)

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.  HITIDE's v1.2.0 user interface is powered by a set of web services which facilitate machine to machine interoperability.  These services, along with additional HITIDE functionality, will be released in the future as development on the HITIDE software package continues at PO.DAAC.

 
OPeNDAP (DODS)
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 (z).

PO.DAAC data currently accessible by POET include:

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

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

 

EOSDIS TOOLS
REVERB-ECHO image
Reverb
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.
 
gcmd.jpg
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.
