AVHRR Land Dataset Program

Project Description
The NOAA/ NASA AVHRR Oceans Pathfinder sea surface temperature data
are derived from the 5-channel Advanced Very High Resolution
Radiometers (AVHRR) on board the NOAA -7, -9, -11 and -14 polar
orbiting satellites. Daily, 8-day and monthly averaged data for both
the ascending pass (daytime) and descending pass (nighttime) are
available on equal-angle grids of 4096 pixels/360 degrees (nominally
referred to as the 9km resolution), 2048 pixels/360 degrees (nominally
referred to as the 18km resolution), and 720 pixels/360 degrees
(nominally referred to as the 54km resolution or 0.5 degree
resolution). Data in different spatial/temporal resolutions are
available from 1985 - 2000.

Global files are available through PO.DAAC ftp or order form and
desired regions are available through the AVHRR Pathfinder subsetting
