GOES West
Question 1
Into what general category of EOS does the instrument fall?
Multispectral imaging and vertical sounder
Question 2
What capture technology is used?
Spin Scan Cloud Camera (SSCC) - frame
Question 3
Is the sensor active or passive?
Passive
Question 4
At what wavelength(s) does the sensor function?
| 1 | 0.52 - 0.72 (visible) |
| 2 | 3.78 - 4.03 (shortwave IR) |
| 3 | 6.47 - 7.02 (upper level water vapour) |
| 4 | 10.2 - 11.2 (longwave IR) |
| 5 | 11.5 - 12.5 (IR window sensitive to water vapour) |
Question 5
What resolution does the sensor have – temporal and spatial?
Temporal
15 minutes temporal resolution, imaging of an entire hemisphere, or small-scale imaging of selected areas.Spatial
Spatial, the satellite is in orbit over a fixed point on the earth's surface
Question 6
Is the sensor carried on an airborne or spaceborne platform? What is that platform – typically?
Spacebourne - Geostationery Satellite
Question 7
Who developed/launched/manages the sensor?
Built by Nasa for NOAA. NASA's Goddard Space Flight Center is responsible for procuring, developing, and testing the spacecraft, instruments and unique ground equipment. NOAA is responsible for overall program, funding, system in-orbit operation, and determining satellite replacement needs.
Question 8
Can data be purchased from service providers?
Yes - Earth Explorer EMWIN data stream broadcast via the GOES-East and GOES-West, the EMWIN data stream is rebroadcast via Peace Sat, on local radio broadcasts and is available on the Internet On GOES-East and GOES-West and on Peace Sat, the EMWIN data stream is analogue broadcast on the WEFAX channel.
Question 9
What products are available?
The GOES system produces a large number of primary data products. They include:
• Basic day/night cloud imagery and low level cloud and fog imagery.
• Upper and lower tropospheric water vapor imagery.
• Observations of land surface temperature data with strong diurnal variation.
• Sea surface temperature data.
• Winds from cloud motions at several levels and hourly cloud-top heights and amounts.
• Albedo and infrared radiation flux to space, important for climate monitoring and climate model validation.
• Detection and monitoring of forest fires resulting from natural causes and/or manmade causes and monitoring of smoke plumes.
• Precipitation estimates.
• Total column ozone concentration (potential data product).
• Relatively accurate estimates of total outgoing longwave radiation flux (potential data product).
Data Product Usage: These data products enable users to accurately monitor severe storms, determine winds from cloud motion, and when combined with data from conventional meteorological sensors, produce improved short-term weather forecasts. The major operational use of 1 km resolution visible and 4 km resolution infrared multi-spectral imagery is to provide early warnings of threatening weather. Forecasting the location of probable severe convective storms and the landfall position of tropical cyclones and hurricanes is heavily dependent upon GOES infrared and visible pictures. The quantitative temperature and moisture and wind measurements are useful for isolating areas of potential storm development.
Major Users: GOES I-M data products are used by a wide variety of both operational and research centers. The NWS's extensive use of multi-spectral imagery provides early warnings of threatening weather and is central to its weather monitoring and short-term forecast function. Most nations in the Western Hemisphere depend on GOES imagery for their routine weather forecast functions as well as other regional applications. GOES data products are also used by commercial weather users, universities, the Department of Defense, and the global research community, particularly the International Satellite Cloud Climatology Project, through which the world's cloud cover is monitored for the purpose of detecting change in the Earth's climate. Users of GOES data products are also found in the air and ground traffic control, ship navigation, agriculture, and space services sectors.
Question 10
At which main application areas is the sensor aimed?
Agriculture, geology, forestry, regional planning, education, mapping, and global change research
List 2 specific projects, where they have been reported, their goals and their outcomes.
