Gas and liquid samples can be collected in specially designed flasks for analysis in the field or at a remote laboratory. Flask collection of samples will augment results for field analysis as checks on field data and for analysis of sample composition not attainable in the field. Flask collection of air for radiocarbon analysis will be undertaken at selected sites employing automated air sampling systems.

The Air Sampling & Monitoring: Hermes 80 V.4A Precision Flask Package (PFP)
Nitrous oxide is ~ 298 times more potent as a greenhouse gas (GHG) relative to CO2. N2O has no significant sinks on land and is destroyed by chemical reactions in the upper atmosphere. Land surfaces are the main source of atmospheric N2O indicating that changes in land-use practices can modify soil emissions and influence N2O concentration in the atmosphere. The uncertainty of sources and sinks of N2O and its atmospheric lifetime limit an accurate budget. Existing data on fluxes of N2O from soils and oceans are insufficient to quantify them in detail. About half of the global N2O emissions are anthropogenic resulting from microbiological processes in soils related to agriculture and tropical forests. The importance of quantification for N2O across PαC projects in combination with CO2 and CH4 is a high priority and should add to diverse ecosystem level data for this important GHG of the tropics.
