Earth Observing System Imagery
3. SVS will allow you to access various EOS datasets and examine them in a
time series. The controls in the SVS dialog box act as DVR-style controls
to run the time-series animation forward, backward, stop, or play.
4. Select the Atmosphere options, then choose the animation for AQUA
MODIS imagery of Hurricane Katrina.
5. Click on the Play button. It will take a couple minutes to download all of
the animation global data.
6. The animation will play, showing several days of imagery from Aqua of
Hurricane Katrina building, then making landfall in the Mississippi Gulf
Coast/New Orleans region.
Question 12.5 Given what you’ve seen of MODIS imagery and the
information in the SVS, should MODIS be used as the sole instrument to
monitor a massive storm formation like Hurricane Katrina? Why or why not?
7. Stop playing the animation, and then from the Atmosphere options,
select Global Atmospheric Carbon Monoxide in 2000. Play the
animation (it should replace the Hurricane Katrina imagery and
cover the entire globe). Make sure to read the SVS description that
accompanies the animation as well. This will show higher levels of
carbon monoxide concentration from the MOPITT instrument onboard
Ter ra.
8. Answer Questions 12.6 and 12.7. (You will have to rotate the globe
while the animation is playing to answer the questions—also keep in
mind the times and dates that are running in the upper-right-hand side
of the screen. You may want to pause or rewind to examine certain dates
in the past.)
Question 12.6 At what dates are the highest concentrations of carbon
monoxide being monitored by MOPITT in Africa and South America?
Question 12.7 Beyond the carbon monoxide levels in Africa and South
America (which were likely generated by wildfires), what other geographic
areas can you see high concentrations of carbon monoxide developing and
spreading from?
9. At this point, you can close World Wind by selecting Exit from the File
pull-down menu.
12.4 Using the NASA Earth Observations (NEO)
Web Resources
1. Open your Web browser and go to http://neo.sci.gsfc.nasa.gov. This
is the Website for NEO (NASA Earth Observations), an online source of
downloadable Earth observation satellite imagery. In this portion of the
lab, you’ll be using EOS imagery in conjunction with Google Earth.
