CALIPSO

• Jeannie Hutchinson
• Digital Imaging

What is CALIPSO?

• Cloud-Aerosol Lidar and Infrared Pathfinder
  Satellite Observations satellite
• What does it do?
• Help scientists answer significant questions and
  provide new information about the effects of
  clouds and aerosols (airborne particles) on
  changes in the Earths climate.

3
Now what does that mean?

• Lidar Light Detection and Ranging
• It measures distance, speed, rotation, chemical
  composition and concentration of a remote target

4
Info

• CALIPSO will fly in a 3-channel lidar with a
  suite of passive instruments in formation with
  Aqua to obtain coincident observations of
  radiative fluxes and atmospheric conditions
• This will greatly improve the ability to predict
  future climate changes

More info

• CloudSat will also fly in formation with CALIPSO
  to provide a comprehensive characterization of
  the structure and composition of clouds and their
  effects on climate under all weather conditions.
• CALIPSO will be monitored and commanded from
  facilities in France.
