TL;DR: In this article, the authors discuss the performance of AIRS and examine how it is meeting its operational and research objectives based on the experience of more than 2 years with AIRS data.

TL;DR: The two main elements of the Atmospheric Infrared Sounder radiative transfer algorithm (AIRS-RTA) are described in this paper: the fast parameterization of the atmospheric transmittances that are used to perform the AIRS physical retrievals and the spectroscopy used to generate the parameterized transmittance.

TL;DR: In this article, an ensemble of temperature and water vapor profiles created from radiosondes launched at the approximate Aqua overpass times, interpolated to the exact overpass time using time continuous ground-based profiles, adjusted to account for spatial gradients within the Advanced Microwave Sounding Unit (AMSU) footprints, and supplemented with limited cloud observations are also constructed.

TL;DR: In this paper, the accuracy of the AIRS radiative transfer algorithm (RTA) was evaluated using data from balloon-borne measurements with RS-90 sensors and frost point hygrometers and Raman lidar measurements of atmospheric water vapor.

TL;DR: The Atmospheric Infrared Sounder (AIRS) is a hyperspectral IR spectrometer orbiting on the EOS/Aqua spacecraft since May 2002 and has been used to detect lower tropospheric sulfur dioxide and ash emitted by an eruption of Mt. Etna (Italy) in plumes which could be tracked over 1000 km from the volcano into North Africa.
