AIRS infrared radiance validation concept using earth scene observations
The atmospheric infrared sounder (AIRS) will fly onboard the NASA earth observing satellite (EOS) polar-orbiting aqua spacecraft.
Atmospheric Infrared Sounder (AIRS): visible and infrared in-flight calibration plan

AIRS Level 1b Algorithm Theoretical Basis Document
The level 1b Algorithm Theoretical Basis Document (ATBD) describes the theoretical bases of the algorithms used to convert the raw detector output (data numbers) from the Atmospheric Infrared Sounder (AIRS), the Advanced Microwave Sounding Unit (AMSU) and Humidity Sounder Brazil (HSB) to physical radiance units and, in the case of AIRS, perform in-orbit spectral calibrations.
The AIRs Team Science Data Validation Plan
This document describes the required validation activities for the AIRS/AMSU/HSB instrument suite in the post-launch period.
Balloon-based Measurements of the Profile of Downwelling Shortwave Irradiance in the Troposphere
Using a helium plus reversible fluid balloon system as the observing platform, multiple profiles of shortwave irradiance between 4 and 10 km were recently obtained over the Los Angeles basin.
Response of the Tropical Boundary Layer to Weak Surface Forcing
During the Tropical Ocean Global Atmosphere Coupled Ocean Atmosphere Response Experiment (TOGA COARE), a series of airborne thermal infrared observations and in situ atmospheric measurements were made near the sea surface through heights exceeding 4 km. Air movements associated with the sea surface temperature and the marine atmospheric boundary layer were studied.
