Overview :

Flask Sampler adalah alat untuk mengukur siklus Gas-gas Karbon dan Isotop diatmosphere.

Instrument Overview :

A suitcase mounted multi-flask array, or Programmable Flask Package (PFP), is used in conjunction with the Programmable Compressor Package (PCP)-a mounted compressor and power module-for programmable time-interval or event-based sampling of atmospheric carbon dioxide (CO2) and other trace gases. This carbon flask collection system flaskis mounted on the Cessna 206 to provide samples at 12 heights or positions. The following features are included:

  • Twelve 0.75L glass flasks in parallel, filled individually
  • Rugged shock mounting of sample flasks
  • Virtually elastomer-free air sample path
  • Stainless steel welded manifolds
  • Automated, motorized valve system
  • Micro-processor controlled customizable program
  • Sturdy travel/shipping case
  • Adaptable to sampling environments that require automated collection of multiple air sample flasks over time.

After the inlet and equipment mounting is installed and airborne, the pilot display will indicate which altitudes to fly to. At the given altitude, the pilot activates the sampling switch on the display and the corresponding sample fills with atmospheric air. Once a PFP is sampled, it is sent back to the ESRL Lab in Boulder, Colorado, for analysis. Another PFP is then sent to the site for future sampling.

Primary Measurements Taken

The following measurements are those considered scientifically relevant. Refer to the netCDF File Header Descriptions (Data Object Design Files) for the list of all available measurements, including those recorded for diagnostic or quality assurance purposes.
