Historical SST (older than 30 days) are also held at the GHRSST Long Term Stewardship and Reanalysis Facility:

You can drill down to specific data sets by navigating the facets such as resolution or processing level at the GDAC.

How good are the data?

NOAA provides a number of services that can be used to evalute the quality of GHRSST data products.

You can evaluate the quality of many GHRSST Level 2, 3 and 4 products using the SST Quality Monitor (SQUAM):

You can also download a collection of in situ data to assess the products yourself using the in situ quality monitor (iQuam):
