The format of GOES I-M imager and sounder data as retransmitted to ground stations.
Industry:Weather
A navigation system based on a constellation of 24 low earth-orbiting satellites having highly accurate clocks and the computational capacity to triangulate positions near the earth's surface. Developed by the U. S. Department of Defense, the system has the capability of determining position to an accuracy of 30–100 m. If systems at two locations are used with long integration times, positions may be determined within millimeters of a known reference position.
Industry:Weather
A Russian satellite system designed to monitor central Asia and the Indian Ocean at 76°E longitude. The satellite reached geostationary orbit in November 1994, but has not produced reliable operational imagery.
Industry:Weather
A time-dependent numerical model of the atmosphere. The governing equations are the conservation laws of physics expressed in finite-difference form, spectral form, or finite-element form. Evolution of the model circulation is computed by time integration of those equations starting from an initial condition. The GCM can be used for weather prediction or for climate studies. Compare atmospheric circulation model, hemispheric model.

A heat index that relates the development of plants, insects, and disease organisms to environmental air temperature. GDD is calculated by subtracting a base temperature from the daily mean temperature and GDD values less than zero are set to zero. The summation over time is related to development of plants, insects, and disease organisms. The reference temperature (base temperature) below which development either slows or stops is species dependent. For example, cool season plants (canning pea, spring wheat, etc. ): base temperature is 40°F (5°C); warm season plants (sweet corn, green bean, etc. ): base temperature is 50°F (10°C); and very warm season plants (cotton, okra, etc. ): base temperature is 60°F (15°C). See degree day, heat unit.
Industry:Weather
A worldwide network of sea level gauges, defined and developed under the auspices of the Intergovernmental Oceanographic Commission. Its purpose is to monitor long-term variations in the level of the sea surface globally by reporting the observations to the Permanent Service for Mean Sea Level.
Industry:Weather
The GLM instrument on the GOES-R series of satellites will provide continuous lightning detection and mapping capabilities from geostationary orbit. The lightning sensor will detect both cloud-to-ground flashes and cloud flashes with a spatial resolution of 5-10 km.
Industry:Weather
A Michelson interferometer being considered for geostationary sounding applications.
Industry:Weather
A suite of radiation sensors designed for MSG that monitor the earth�s radiation budget by simultaneously monitoring incoming solar radiation, solar radiation reflected at the top of the atmosphere, and thermal radiation emitted by the Earth.
