GV Exterior Payload

The instrument suite on board the GV is specific to the science conducted during HIPPO. Several inlets take in air samples that can be distributed to up to three instruments. Click on the links below to get detailed information about each instrument.

Once the campaign is over, all of the instrumentation is removed so the upload of the new instrument payload for the next campaign may begin. Many instruments are used on other field projects but need to be removed in order to start the next upload in a systematic manner.

HIPPO is a landmark study for many reasons, not the least of which is it is the first time scientists have systematically mapped global distribution of carbon dioxide and other greenhouse gases in the atmosphere, covering the full troposphere in all seasons and multiple years.
