AIRS and AMSU: Trace Gases (CO2, CO, CH4, O3...); Level 3
Main content

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

Key Strengths

Near global coverage with high horizontal and vertical resolutions and frequent sampling
