GOES 3.9 µm Channel


Other contributions by: Dan Bikos, Jeff Braun, Don Hillger, Bernie Connell, Scott Bachmeier and Scott Lindstrom


This is an introductory session meant to complement CIRA's 3.9 µm tutorial, but is a good review for any forecaster.


  1. Review the science behind the 3.9 µm channel
  2. Discuss the many possible applications, including fog detection, fire detection, and snow/low cloud differentiation
  3. Look at a number of examples
  4. Preview what's to come with future sensors


This is a basic course. CIRA's 3.9 µm tutorial contains complementary information.
