HIPPO II Flight #2 :: Northern Polar Regions

November 2, 2009HIPPO RF02

The NSF/NCAR G-V flew from Anchorage, AK towards the North Pole and back to Anchorage on Research Flight #02.


There were many objectives during the flight, but one important one was to sample the atmosphere as far north as they could during daylight. Steve Wofsy, HIPPO Principal Investigator explains why this is important for the HIPPO project:

This is operational: We wish to fly low, and not in clouds, both for safety reasons and because some instruments don't like to ingest liquid or frozen water. In the dark, you cannot see if there are clouds near the surface, and in the cold arctic region there very often are clouds near the surface.

In fact, there was plenty of light on our whole trip. At 80N we had a full moon directly ahead of us as we flew towards the pole, and the sun was just below the horizon to the south.

There was also a ton of pollution from Asia--the atmosphere was full of dark material, with high concentrations of CO. It is not pleasant to think that this remote area of the earth is grossly polluted, but that is the truth much of the time.

About HIPPO

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.
