ghgflask

The carbon flask collection system (FLASK) samples atmospheric carbon dioxide and other trace gases. It comprises a suitcase-mounted array of flasks, or Programmable Flask Package (PFP), and a compressor and power module, or Programmable Compressor Package (PCP), to do programmable time-interval or event-based sampling. The FLASK system is mounted on a Cessna 206 aircraft to take samples at 12 heights or positions.

A pilot display indicates sampling altitudes. At a given height, the pilot activates the sampler and atmospheric air fills the corresponding flask. Sampled PFPs are analyzed in the lab to determine gas concentrations and isotope ratios.

Methane concentration
Isotopic ratio of C13 in CH4
Carbon monoxide concentration
Carbon dioxide concentration
Hydrogen concentration
Nitrous oxide concentration
