Methodology ยท Imaging spectroscopy
SWIR absorption - point-source
Detects gas absorption features (CH4, CO2, CO) at SWIR wavelengths from a single point or facility source; good for industrial emissions monitoring and leak detection.
How it works
Uses column-averaged gas concentration retrieval from SWIR absorption bands (~1600-2300 nm). [Wikipedia: Shortwave infrared](https://en.wikipedia.org/wiki/Shortwave_infrared)
Topics this serves
- Industrial emissions well suited
- Methane (CH4) well suited
- CO2 adequate
Existing implementations
Capable, undemonstrated
Related methodologies
-
Estimates area-integrated greenhouse gas flux over agricultural, wetland, or basin-scale regions; good for national inventory support and carbon accounting.
-
Wide-area survey for anomalous methane or CO2 concentrations at coarse spatial resolution; good for prioritising follow-up with finer sensors.
-
Identifies surface materials or land-cover classes from full spectral fingerprints; good for geology, vegetation stress, and mineralogy mapping.
