Recently the PO.DAAC made available new GHRSST sea surface temperature
datasets in the new GDS2 data format (netCDF4) from the NAVO data provider.
See the announcement here:

The data stream for the GDS1 (netCDF3) NAVO counterparts referenced in the
announcement will no longer be produced after 1 Feb 2015.
Please begin using the GDS2 versions as soon as possible. The
previous GDS1 datasets will always remain accessible at the NOAA National
Oceanographic Data Center (NODC) at:
