VOLCANO AEROSOL CLOUD
SATELLITE:"AEROSOL CLOUD IS GONE"
JOE NOVICE:"AEROSOL CLOUD STILL THERE"
Can you describe any of the three methods
Joe used to detect the aerosol?
Satellites provide global coverage of clouds, water vapor, dust, smoke and the
ozone layer. The colorful images provided by the data from these satellites
looks very impressive. But satellite instruments don't always stay calibrated
and problems can occur when satellite orbits drift. Amateur scientist, Joe
Novice learned about this when he heard a satellite scientist say that the
global aerosol cloud formed by the eruption of a giant volcano had dissipated
much sooner than expected. Joe suspected the satellite was simply wrong,
but he was not a satellite scientist. How did he use some everyday items and
several electronic components to prove he was right?
What's your solution? See if you are correct at
where you will find all three of Joe's solutions.
