  1. Due Wednesday March 20
  2. Answer in complete sentences and on separate sheets.
  3. Show all work (number equations, and lay out all steps neatly)
  4. This lab is worth 100 points

Lab 1: Geosynchronous (GOES) Satellite Basics

 

Resources helpful for this inclass Lab exercise:

Question 1: Background and appropriate equations. (Basically, a summary of this is on pages 16-17 of K&VH)

Question 2: NOAA Satellite Tutorial Class textbooks

Question 3: NOAA Satellite Tutorial

Question 4: GOES Status, GOES Spacecraft Operations

Question 5: GOES and POES Launch Schedule

Question 6: NOAA Background and NOAA imager information

Question 7: Wien's Law where b=Planck's constant is 2.90 X 106 nm K, 1 micrometer is 1000 nanometers

1. Question 1: Group Exercise . (30 points)

2. Expand the acronym "GOES"? (5 points)

3. Over what latitudes and longitudes are GOES 13 and 15 parked, and which is GOES-E and which is GOES-W? (8 points)

4. When were the GOES 13 and GOES 15 satellites launched? (4 points)

5. GOES 14 used to be GOES-W. Over which longitude is it currently located and what is its function? (8 points)

6. Make a table to hold the answers to the following questions, regarding Imager channels, where each channel is identified by its integer channel number (eg: 1, 2, etc.) (15 points)

  1. What is the name for each channel?
  2. What is the range of wavelength captured by each channel?
  3. State whether each channel measures measure emitted or reflected radiation (by placing E or R in the correct spot in the table you are creating)?

7. Provide the following information (18 points)

  1. For each channel, state what the BEST horizontal resolutions are (i.e., Field of View at Nadir, km on the earth's surface)?
  2. Which channel(s) would be best to "detect"* sea surface temperatures and why?
  3. Which channel(s) would be best to detect atmospheric water vapor and why?

8. Meteorologists Only: Channel 5 covers a range of infrared energy from a wavelength of 11.5 micrometers to 12.5 micrometers. What is the range of blackbody temperatures (in C) of an object emitting radiation in this wavelength range? Provide an example of a body radiating in this range (important in meteorology). (12 points)

Oceanographers Only: Channel 4 covers a range of infrared energy from a wavelength of about 9.8 micrometers to 11.2 micrometers. What is the range of blackbody temperatures (in C) of an object emitting radiation in this wavelength range? Provide an example of a body radiating in the low end and high end of this range (important in oceanography). (12 points)

*The satellite imagers do not directly detect temperature (or water vapor etc.) but do directly detect the radiation emitted by water molecules in the sea surface of atmosphere.
