The Advanced Very High Resolution Radiometer (AVHRR) instrument flies on the
NOAA Polar Operational Environmental Satellites (POES) and the European
MetOp Satellites. AVHRR is used to image a large variety of Earth phenomena,
including vegetation, clouds, dust, snow, ice, fire, and surface temperature.
Sea surface temperature (SST) is generated in near real-time using AVHRR's
infrared channels by NOAA/NESDIS from High Resolution Picture Transmission
(HRPT) overpasses (1.1 km at nadir) using Seaspace's TeraScan software and
NOAA's multi-channel regression algorithm (Li et al., 2001a & 2001b). With
the various satellite instances, overpasses occur at roughly 1:30am,
9:30am, 1:30pm, 9:30pm (local time) per day.
The individual daytime and nighttime SST scenes from each operational POES
and MetOp satellite are composited by NOAA CoastWatch into daily combined
day-night mean grids for the U.S. east coast (at approximately 1.25 km).
The daily gridded scenes are then composited into 3-day, 7-day, monthly,
seasonal and annual average grids.
The data time series spans 2008 to the present.
