U.S. Naval Oceanographic Office (NAVOCEANO)'s GOES satellite hourly Sea Surface Temperature (SST) retrievalsEntry ID: NAVOCEANO_GOES_SST_1
Abstract: U.S. Naval Oceanographic Office (NAVOCEANO)'s Geostationary Operational
Environmental Satellite (GOES) Sea Surface Temperature (SST) hourly retrievals.
The data set includes data from three satellites: GOES-8 (decommissioned in 200
3), GOES-10 (GOES East) and GOES-12 (GOES West).
GOES satellites provide the kind of continuous monitoring necessary for
intensive data analysis. They circle the ... Earth in a geosynchronous orbit, which
means they orbit the equatorial plane of the Earth at a speed matching the
Earth's rotation. This allows them to hover continuously over one position on
the surface. The geosynchronous plane is about 35,800 km (22,300 miles) above
the Earth, high enough to allow the satellites a full-disc view of the Earth.
Because they stay above a fixed spot on the surface, they provide a constant
vigil for the atmospheric "triggers" for severe weather conditions such as
tornadoes, flash floods, hail storms, and hurricanes. When these conditions
develop the GOES satellites are able to monitor storm development and track
GOES satellite imagery is also used to estimate rainfall during the
thunderstorms and hurricanes for flash flood warnings, as well as estimates
snowfall accumulations and overall extent of snow cover. Such data help
meteorologists issue winter storm warnings and spring snow melt advisories.
Satellite sensors also detect ice fields and map the movements of sea and lake
Currently, the United States is operating GOES-10 and GOES-12. Each satellite
is equipped with a GOES Imager radiometer which collects information on 5
channels (1 visible and 4 infrared). The scans are every hour with an
Instantaneous Field of View (IFOV) of 4 km. Each satellite views almost a third
of the Earth's surface: one monitors North and South America and most of the
Atlantic Ocean, the other North America and the Pacific Ocean basin. GOES-12
(or GOES-East) is positioned at 75 W longitude and the equator, while GOES-10
(or GOES-West) is positioned at 135 W longitude and the equator. The two
operate together to produce a full-face picture of the Earth, day and night.
Coverage extends approximately from 20 W longitude to 165 E longitude.
Brightness temperatures from the 5-channel instrument are regressed against
buoy data to derive a set of coefficients. These coefficients are then used to
convert the brightness temperatures to an SST measurement. The theory itself is
very similar to the non-linear algorithm used to process AVHRR-derived SSTs.
