Summary of the guide, instruments, spectra, algorithm & data
Describes the intention of the AIRS guide and provides overviews of the AIRS instrument, spectra, algorithms and data.
Aqua Spacecraft
AIRS flies aboard NASA's Aqua satellite, this section provides summary information about Aqua.
Instrument Suite: AIRS, AMSU, HSB
Provides details about the instruments that make up the AIRS suite (AIRS, AMSU, HSB). Includes viewing characteristics, stability and performance. The visible imager for AIRS is also discussed.
Observing Geometry, Data Granules, and Sample Radiance Observations
Includes details on the AIRS ascending and descending (day and night) observations, data granules, and imagery examples.
AIRS and other Hyperspectral IR Sounders
Table that summarizes the differences between the spaceborne hyperspectral infrared sounders.
AIRS and Model Reanalysis Data Sets
Includes discussion of the advantages and disadvantages of using AIRS retrieval over reanalysis data.
Data Processing Steps and Levels
Describes the steps involved in processing the AIRS data, from Level 0 to Level 3. Includes material on vertical representation (layers and levels) and vertical resolution, and gridding.
Data Organization
Overview that describes the Level 1, 2, and 3 processing flow and processing system for the AIRS data. Includes a table of data product short names and current data processing versions.
Documentation Organization
Overview of the general and level-specific user guides including ATBDs, channel properties and calibration documentation.
Appendix A: AIRS Products and File Names
Summary descriptions and links to AIRS products, including Level 1 radiance products, Level 2 and 3 geophysical products from both the AIRS-team and CLIMCAPS retrieval systems, near-real-time products, and CO2 and precipitation products.
