Archived Satellite Imagery

Due beginning of class, Monday 22 April 2013. (100 points)

A. U.S.Navy Tropical Cyclone Imagery Archive

Access the U.S. Navy Tropical Cyclone Imagery Archive, linked to from the Class Website. We will get imagery for Hurricane Katrina. We will run through this in class, but you will need to do this at home, and save the images (and print them) locally from home.

  1. The entry point for Katrina should have a default image of the storm's history. Click on it and save that image to disk. Print a color copy (if possible) at home. (10 points)
  2. Note the links for the Visible and Infrared Imagery in the far right hand table box. Katrina was at its most intense at 2245 UTC 28 Augus 2005. Obtain a 1 km Visible Image (remember to click on it to get the largest, highest resolution image) and a 1 km Infrared Image (Choose Color) (remember to click on it to get the largest, highest resolution image) for those times and save them to disk. Print a color copy of each. (20 points)

B. CLASS Archive

Access the CLASS website, linked to from the Class Website. We will get imagery for the southern Great Plains for May 22, 2011 (the day of the Joplin EF5 tornado). (70 points)

  1. Set yourself up with an account (it's free) with the CLASS system.
  2. Select from the choices on the right margin "Environmental Data from the Geostationary Satellites". We will want to get a visible (Channel 1) and enhanced infrared (Channel 4) satellite image for 2200 UTC 22 May 2011. It's best to choose a range of times, say 2200 to 2230 UTC. Also, for this exercise, choose JPEG. Make sure you focus on the southern Great Plains, say on Kansas, Missouri, Oklahoma and Arkansas.
  3. Print your results.
