4 km AVHRR Pathfinder Available Data

Work is underway to make these Pathfinder V5 data available through a wide variety of mechanisms, in an attempt to serve the broadest possible array of users. These mechanisms include:

1. Direct FTP Access: If you know what you want and have a large number of files to download then this is a good approach. Simply point your favorite ftp client to ftp://data.nodc.noaa.gov/pub/data.nodc/pathfinder and begin downloading files.
2. Simple Web Access: Simply click on http://data.nodc.noaa.gov/pathfinder and begin browsing through the file hierarchy. Clicking on any of the files will prompt you to download that file or will launch any application you might have associated with HDF files. If you want to just take a look around and see what is there, or if you know which file or small number of files you want to download, then this is a good approach.
3. OPeNDAP Access: These data are also served using OPeNDAP (formerly called the Distributed Oceanographic Data System or DODS) server so you may access all of these data using that distributed data access system. The base URL is http://data.nodc.noaa.gov/cgi-bin/nph-dods/pathfinder In addition, you may simply follow the links provided in the table below to access the OPeNDAP directory listings. For a listing of OPeNDAP clients which you can use to access the 4 km Pathfinder data (as well as any other OPeNDAP-enabled data sets), please see the OPeNDAP * web site and follow the link called "Download". Examine the list of "Clients" for various mechanisms to access and display the data directly using OPeNDAP. For example, the OPeNDAP Data Connector * is an excellent standalone client which will allow you to quickly search, access, browse, and even generate images of the Pathfinder SST data.
4. Live Access Server (and GoogleEarth): Our colleagues at NOAA's South West Fisheries Science Center, Environmental Research Division have established an excellent Live Access Server which serves many datasets, including some of the AVHRR Pathfinder V5 dataset. Go to: OceanWatch Live Access Server - this customized interface includes GoogleEarth access. They also have a more traditional Live Access Server interface - for direct access to the AVHRR Pathfinder V5 data through it go to http://las.pfeg.noaa.gov/OceanWatch/servlets/dataset?catitem=18.
5. Low Resolution Browse Images: For 1985-2006, Simply click on http://data.nodc.noaa.gov/pathfinder/Version5.0/browse_images and begin browsing through low resolution JPEG images for every data file on the system. Browse imagery for interim 2007 data are also available, at: http://data.nodc.noaa.gov/pathfinder/Version5.0_interim_NOAA18/browse_images and begin Note the browse images for 1985-2001 are more coarse, showing 1 out of every 32 pixels, than those for 2002-2007, for which 1 out of every 16 pixels are displayed.
   
6. Climatologies: Corresponding climatologies based on the 1985-2001 base period are available via HTTP, FTP, and OPeNDAP. More information on these climatologies is found in the README.txt document. The URLs for the climatologies are similar to the Version5.0 data, but with _Climatologies appended:
   • HTTP: http://data.nodc.noaa.gov/pathfinder/Version5.0_Climatologies
   • FTP: ftp://data.nodc.noaa.gov/pub/data.nodc/pathfinder/Version5.0_Climatologies
   • OPeNDAP: http://data.nodc.noaa.gov/cgi-bin/nph-dods/pathfinder/Version5.0_Climatologies

• PO.DAAC FTP Server: ftp://podaac.jpl.nasa.gov/sea_surface_temperature/avhrr/pathfinder/data_v5 contains daily all-pixel SST data with quality flags from 1985-current.
• PO.DAAC POET : http://podaac.jpl.nasa.gov/poet provided sophisticated online display and subsetting capabilities.
