ANSWERS TO REVIEW QUESTIONS A1.   Zero  degrees  (0°). A2.    Geostationary, earth-synchronous, or geosynchronous. A3.    Ascending-node. A4. The satellite’s orbit is synchronized with the movement of the sun across the earth’s surface. A5. 0200 local. A6. Major changes in a satellite’s apogee and perigee positions are caused by the shape of the earth, and the gravitational pull of the earth, sun, and moon. A7. Atmospheric sounders provide vertical temperature and moisture profiles, and atmospheric stability data. A8. Geostationary satellites are ideal for making large-scale, frequent observations over a fixed geographical area A9.    GOES East. A10.    Polar-orbiting. A11. Because of their relatively low-altitude orbits, polar-orbiting satellites provide higher resolution data than geostationary satellites. They also provide imagery for the high- latitude and polar regions. A12. 2700 km (1500 nmi). A13. Fleet Numerical Meteorology and Oceanography Center (FNMOC). A14. METEOSAT A15. A   radiometer. A16.    The sensor with 1 kilometer spatial resolution. A17.    The  cold  object. A18.    Longwave radiation. A19.    Red. A20. Sand. A21. Infrared  imagery  is  available  day  and  night.  It  is  also  an  excellent  tool  for oceanographic analysis and is also helpful for identtfiing upper-level features. A22. White. A23. Relatively light gray shades. A24.    Water vapor imagery produces better definition of the moisture distribution and circulation patterns in the upper atmosphere. A25.    An enhanced satellite image provides better definition, which allows the user to view specific  details. 1-38
