GEOSTATIONARY OPERATIONAL ENVIRONMENTAL SATELLITE (GOES) Telemetry and Communications
نویسندگان
چکیده
The GOES satellites are multifunctional satellites whose primary function is to provide continuous measurements of the earth’s surface and atmosphere from two geostationary orbit locations: 75EW and 135EW. This objective is accomplished with the Visible infrared spin scan radiometer Atmospheric Sounder (VAS). The atmospheric sounder is a new feature which will add a third dimension to the photographs of the earth seen nightly by TV newscast viewers. The satellite also contains a Space Environment Monitor (SEM) which includes three instruments: a magnetometer, a solar X-ray sensor and an energetic particle sensor (EPS), which monitor solar flares and near earth space environment. The satellite contains a communications system which, in addition to transmitting VAS, SEM and housekeeping data to earth, provides relay capabilities for the stretched VAS and weather facsimile (WEFAX) data, as well as for the Data Collection Platform (DCP). A sketch of the satellite is given in Figure 1.

Validation of Cloud Properties Derived from GOES-9 Over the ARM TWP Region
Satellite data are essential for monitoring clouds and radiative fluxes where ground-based instruments are unavailable. On April 24, 2003, the ninth geostationary operational environmental satellite (GOES-9) began operational coverage of the Tropical Western Pacific (TWP), replacing the failing fifth geostationary meteorological satellite (GMS-5). The GOES-9 imager provides the opportunity for ...
متن کاملSatellite-based estimates of longwave radiation for agricultural applications
Geostationary satellites provide information that enables frequent, routine and cost-effective estimates of both downwelling longwave radiation and incident solar radiation for use by agricultural and other applications, at a resolution that cannot be practically matched by ground-based measurements. We develop a new parameterization for downwelling longwave radiation at the earth’s surface tha...
متن کاملThe GOES Time Code Service, 1974–2004: A Retrospective
NIST ended its Geostationary Operational Environmental Satellites (GOES) time code service at 0 hours, 0 minutes Coordinated Universal Time (UTC) on January 1, 2005. To commemorate the end of this historically significant service, this article provides a retrospective look at the GOES service and the important role it played in the history of satellite timekeeping.

This paper describes the techniques used to obtain sea surface temperature (SST) retrievals from the Geostationary Operational Environmental Satellite 12 (GOES-12) at the National Oceanic and Atmospheric Administration’s Office of Satellite Data Processing and Distribution. Previous SST retrieval techniques relying on channels at 11 and 12 mm are not applicable because GOES-12 lacks the latter ...

Cloud absorption of solar radiation has been the focus of several recent studies and the Atmospheric Radiation Measurement Program (ARM) Enhanced Shortwave Absorption Experiment (ARESE). One of the methods for studying cloud absorption has employed the analysis of coincident surface and satellite measurements. To provide consistency with the earlier satellite results, this paper presents the re...
