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

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
