Metr 415/715 Monteverdi Problem Set 1: Answer Key

 

Please make sure you answer in complete sentences and on separate sheets of paper.

 

Question 1:

 

I. Information Desired

 

Orbital radius (height above surface of earth) of geostationary satellite.

 

II. Equations Needed

 

                                    (1)

 

                        (2)

 

                                                       (3)

 

III. Relations or Constants Needed

 

(4)

 

 

IV. Solution

 

For a geosynchronous orbit,

 

Fc = Fg                                                                (5)

 

Insert (1), (2), (3) and (4 b, d and e) into (5) and solve for R3

 

R3=7.501 X 1022  m3                     (6)

 

R=4.217 X 107  m3                       (7)

 

Substitute (4a and b) into (7) and solve for h

 

h=3.58 X 107  m3                          (8)

 

Question 2: The abbreviation GOES expands out to "Geostationary Operational Environmental Satellite."

 

Question 3: The subsatellite point for GOES-11 (aka GOES W) is 0o, 135o W and for GOES-32 (aka GOES E) is 0o, 75o W.

 

Question 4: The Cape Canaveral launch dates for GOES-11 (GOES-W) and GOES-13 (GOES-E) were May 3, 2000 and May 24, 2006, respectively.

 

Question 5: South America

 

Question 6:

 

Channel Wavelength (microns) Detection (Emitted or Reflected Radaition) Resolution (km) Operational Usefulness

1 Visible

0.55-0.75 R 1 km (standard) Cloud, dust, pollution
2 Infrared (short end) 3.8-4.0 E 4 km Fog,
3 Infrared (water vapor) 6.5-7.0 E 8 km Precipitable water
4 Infrared (cloud emittance) 10.2-11.2 E 4 km Deep (precipitation-producing cloud bands), Thunderstorms
5 Infared (land surface emittance) 11.5-12.5 E 4 km SST, volcanic dust
