CDIAC HIPPO Data Archive ::
This Carbon Dioxide Information Analysis Center (CDIAC) HIPPO data archive provides integrated measurement data products and user documentation. Files are in ASCII text format. Products include:

  • A comprehensive merged product at 10-second resolution for all high-rate measurements
    (40 measurements of 26 unique species, not counting flask measurements)
  • Combined results from all discrete whole air sample and gas chromatograph measurements (77 unique species)
  • Pressure-weighted mean column concentration data -- total, 10 km and 100 m intervals

Included are results from 90+ species from six categories, all with navigation and atmospheric structure data: 1) greenhouse gases and carbon cycle gases, 2) ozone and water vapor, 3) black carbon and aerosols, 4) CFCs, HCFCs, and HFCs, 5) light hydrocarbons and PAN, and 6) sulfur gases and ocean-derived gases

EOL HIPPO Data Archive ::
The Earth Observing Laboratory (EOL) HIPPO data archive provides component data, documentation, and information, including:

  • Photos, imagery, and movies from aircraft-mounted camera with time-synchronized navigation and state parameter data
  • Publications derived from HIPPO data, meeting agendas, and presentations
  • Investigator-provided quality-assured individual instrument data files
  • Supporting data sets (e.g. operational satellite, model output, global observations, etc.)
  • Ancillary flight information, field catalogs, data quality reports, software, and documentation
  • Pole-to-pole atmospheric cross-section plots of chemical species

HIPPO V :: 9 August - 9 September, 2011



brittvideo.jpgThe “HIAPER Pole-to-Pole Observations (HIPPO) of Carbon Cycle and Greenhouse Gases Study” will measure cross sections of atmospheric concentrations approximately pole-to-pole, from the surface to the tropopause, five times during different seasons over a three year period. A comprehensive suite of atmospheric trace gases pertinent to understanding the Carbon Cycle will be measured. The program will provide the first comprehensive, global survey of atmospheric trace gases, covering the full troposphere in all seasons and multiple years.

SeaIce_video_t.jpgSampling Black Carbon Over Sea-Ice and Open Leads
The HIPPO campaign presents an unparalleled opportunity to sample the atmosphere, as the name suggests literally from pole-to-pole, from 500 feet about the surface of the ocean to 45,000 feet in altitude. (Learn more...)
CO2 Instrument VideoCarbon Dioxide Instrument
The CO2 instrument draws air in through a rear facing inlet, in one of the the HIMIL which we’ll go over and take a look at, there’s one hanging on the bottom of the plane, it’s easy to see. (Learn more...)

This image also is showing a color representation of one of the species that we measure in the HIPPO experiment, this one is water vapor...(Learn more...)

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.
