AIRS provides satellite retrieval of mid-tropospheric carbon dioxide even under cloudy conditions, without the use of a priori information from models. AIRS retrievals use cloud-cleared thermal IR radiance spectra in the 15 micron band with an accuracy better than 2 ppm. AIRS retrievals have been used to produce global maps of carbon dioxide and other trace gases including ozone, methane, and carbon monoxide.
Key Strengths:
- Near global coverage with high horizontal and vertical resolutions and frequent sampling
Key Limitations:
- Inconsistent sampling with latitude
