The High Resolution Infrared Spectroscopy Group conducts basic experimental and theoretical research into the absorption of radiation by gases for the purpose of determining the molecular spectroscopic parameters needed for the design and interpretation of NASA's field measurement programs related to the environment of the earth's and other planetary and stellar atmospheres.
Research Projects
Corrections and Additions for the HITRAN Water Vapor Spectrscopic Database
Unique Facilities and Instrumentation
Spectroscopy Laboratory
- Spectra can be recorded at very high spectral resolution with optical absorption path lengths up to 2 kilometers.
- Spectra can be recorded down to 57 deg K with an optical absorbing path of 30 cm.
- In-house developed software greatly facilitated the speed of the spectral data analysis.
Magnetic rotation spectrometer (in development)
- Airborne instrument with ultra-sensitivity (parts/trillion by volume) for the detection of trace concentrations of molecules.
