The OBPG has recently put on line a new data distribution server:

https://oceandata.sci.gsfc.nasa.gov

Unlike the existing FTP data distribution server ([url=ftp://oceans.gsfc.nasa.gov]ftp://oceans.gsfc.nasa.gov[/url]),
which allows access to Level 3 data for all supported missions and a limited
set of Level 1 and Level 2 MODIS data, this new server allows users HTTP
access to EVERY file within our archive.

This new HTTP-based server is intended to replace the functionality of the
existing FTP-based server.  To aid in that transition, the website is
organized in a manner that generally replicates the FTP directory tree
structure (although some minor differences exist).

Examples of how to retrieve data in bulk can be found here.

In addition, it includes a file search utility to allow users the ability to
locate data without manually traversing the directory tree.
(https://oceandata.sci.gsfc.nasa.gov/api/file_search/)

The file search utility also provides a non-interactive search capability.

Please use https:// rather than http. Plain http:// is no longer supported.
