PODAAC_MCC

Metadata Compliance Checker  Version: 1.1

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. It also checks GHRSST version 2 data formats as applicable.  It works with both user locally uploaded data as well as data that are accessible via OPeNDAP. The MCC is based on open source software originally developed by NOAA that has been extended with additional functionality and reporting.

PODAAC_Drive

PO.DAAC Drive Version: 1.0

PO.DAAC Drive is a new way of browsing data at PO.DAAC. Drive is an FTP alternative that allows users to access data via browser and command line as has been traditionally done, but can also allow users to mount the remote data to your own computer, seeing the data as if you had the entire PO.DAAC archive mounted on your own machine! A few simple steps will have you up and running with PO.DAAC Drive.

THREDDS Version: 4.6.3

A new version 4.6.3 of the Thematic Realtime Environmental Distributed Data Services (THREDDS) Data Server was recently deployed on the User Acceptance Tools (UAT) Server and was reconfigured to always read directly from the file system for improved performance. It reads from file server if data already uncompressed or un compresses the datasets to ZFS.

THREDDS is a web server that provides metadata and data access for scientific datasets, using a variety of remote data access protocols.

LAS Version: 8.4

A new version 8.4.3 of the Live Access Server (LAS) was recently deployed on the User Acceptance Tools (UAT) Server for evaluation and testing.

LAS is a web-based L3 data visualization and subsetting tool, designed to provide flexible access to geo-referenced scientific data. It enables the web user to: visualize data with on-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.

For a guide and tutorial to using LAS see  ftp://podaac.jpl.nasa.gov/misc/web/tutorials/las/
