文摘
- •
The sample design of soil flux surveys must be fit for purpose.
- •
An irregular sampling grid is ideal for quantification of surface emissions.
- •
Ratios of soil gases from portable measurements can be used to infer CO2 source.
- •
Subsurface gas migration limits usefulness of point measurements for leak detection.
