Cloud tops
Name 3 advantages of a geostationary satellite which provides better tracking of localized hazardous weather conditions.
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.

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.
