Source: The 4 km Pathfinder effort at the National Oceanic and Atmospheric
Administration (NOAA) National Oceanographic Data Center (NODC) and the
University of Miami's Rosenstiel School of Marine and Atmospheric
Science (RSMAS) is an extension of, and improvement on, the sea surface
temperature (SST) fields from the NOAA/NASA AVHRR Oceans 9km Pathfinder
dataset. In this 4 km Pathfinder project, some important shortcomings in
the original 9 km data have been corrected, and the entire time series
has been reprocessed at the 4 km Global Area Coverage (GAC) level, the
highest resolution possible globally. Twice-daily SST and related
parameters from 1985-2001 have been produced, as well as temporal
averages for 5-day, 7-day, 8-day, monthly, and yearly periods.
Low-resolution .JPEG browse images are available for each dataset. These
data products and accompanying Federal Geophysical Data Committee (FGDC)
metadata records were produced and archived for distribution at the NOAA
National Oceanographic Data Center in 2004.  The collection was updated 
in 2008 to include final V5 data for 2002-2006, as well as interim data for
2007.

In 2009, all data from NOAA-18 were reprocessed due to a minor error with the
AVHRR instrument on board that satellite.  Affected data include final data
from day 156 of 2005 through 2006, and interim data for 2007.  New data can
be found in the 02-version directory of the following accessions:
