Hydrosphere (water) Atmosphere (air) Lithosphere (land) |
|
|
What 4 broad categories of features are generally visible on GOES satellite images?
|
Land surfaces
Ocean surfaces Snow/ice surfaces Cloud tops |
|
|
Name 3 advantages of a geostationary satellite which provides better tracking of localized hazardous weather conditions.
|
Precision
Accuracy Frequency (every 15 min.) |
|
|
What is one big difference between a POES satellite & a GOES satellite?
|
POES conver the entire earth traveling north-south passing very close to the poles.
GOES appear sationary above a specific point of earth & follow the earth as they rotate. |
|
|
What does the acronym POES represent?
|
Polar Operational Environmental Satellite
|
|
|
What does the acronym GOES mean?
|
Geosynchronous Operational Environmental Satellite

|
Greenwich Mean Time (GMT) is now called Universal Time Coordinates (UTC).

|
Name two sources of radiation coming from features on earth, such as: oceans, land, cloud tops, snow/ice.
|
Relfected (visible) sunlight (depends on intensity of light striking a feature & a feature's reflectivity (or albedo)
Emitted IR radiation (intensity depends on temperature of feature) |
|
|
Many scientists believe that Ozone is on the rise in the atmosphere. Is this true?
|
Yes, but others say it is part of a cycle of years. With better satellite imaging & more data collected for comparison, scientists hope to validate their theories.
|
|
|
What is albedo?
|
Albedo is the proportion of visible light striking an object or surface that the object or surface reflects.
|
|
|
What are the Primary Colors of Light?
|
Red, Green, Blue
|
|
|
What organization is dedicated to studies about climate change?
|
National Oceanic & Atmospheric Administration (NOAA)
|
|
|
Is it true that a geostationary satellite looks at all times at the same location as it follows the earth's movement?
|
Yes
