podaacDatasets.owl is an extension of the SWEET (http://sweet.jpl.nasa.gov) https://sweet.jpl.nasa.gov/2.3/reprDataProduct.owl#Dataset class which uses the Directory Interchange Format (DIF) content metadata, a specific set of attributes for describing Earth science data. Currently DIF is used at NASA JPL's PO.DAAC to model oceanographic datasets. The DIF specification provides the data model which we use to described individual instances of https://sweet.jpl.nasa.gov/2.3/reprDataProduct.owl#Dataset.
A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced as a retrospective dataset (four day latency) at the JPL Physical Oceanography DAAC using wavelets as basis functions in an optimal interpolation approach on a global 0.011 degree grid. The version 4 Multiscale Ultrahigh Resolution (MUR) L4 analysis is based upon nighttime GHRSST L2P skin and subskin SST observations from several instruments including the NASA Advanced Microwave Scanning Radiometer-EOS (AMSRE), the Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Aqua and Terra platforms, the US Navy microwave WindSat radiometer and in situ SST observations from the NOAA iQuam project. The ice concentration data are from the archives at the EUMETSAT Ocean and Sea Ice Satellite Application Facility (OSI SAF) High Latitude Processing Center and are also used for an improved SST parameterization for the high-latitudes. This data set is funded by the NASA MEaSUREs program (http://earthdata.nasa.gov/our-community/community-data-system-programs/measures-projects), and created by a team led by Dr. Toshio Chin from JPL.

GCMD-DIF is the data model used at NASA JPL's PO.DAAC to describe Datasets.
The Directory Interchange Format (DIF) content metadata is a specific set of attributes for describing Earth science data. From its conception in the late 1980’s as a way to document and exchange information on scientific data to its implementation in the Global Change Master Directory (GCMD), the DIF has evolved to serve the user community in the discovery, access and use of Earth science and related data.
http://mudrod.jpl.nasa.gov/podaacDatasets.owl#PODAACDataset is a subset of http://sweet.jpl.nasa.gov/2.3/reprDataProduct.owl#Dataset which complies with the NASA Global Change Master Directory Directory Interchange Format (GCMD-DIF) data model described at http://semanticportal.esipfed.org/ontologies/GCMD-DIF
