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 data for 2002-2006,
and again in 2011 to include value-added, cloud-screened
products in HDF4. These products contain daytime, nighttime, and day-night
averaged data of quality flags 4-7 only, as well as standard deviation and
pixel count information. They have been produced from the original Pathfinder
Version 5 data by NODC for Daily, 5-day, 7-day, and monthly temporal averages
at 4km and one degree spatial resolution, as well as five degree spatial
resolution for monthly products.
