The Atmospheric Infrared Spectrometer (AIRS) Science Processing System is a collection of computer programs, denoted product generation executives (PGEs), for processing the readings of the AIRS suite of infrared and microwave instruments orbiting the Earth aboard NASA 's Aqua spacecraft. Following from level 0 (representing raw AIRS data), the PGEs and their data products are denoted by alphanumeric labels (1A,1B, and 2)that signify the successive stages of processing. Once level-0 data have been received, the level-1A PGEs begin processing, performing such basic housekeeping tasks as ensuring that all the Level-0 data are present and ordering the data according to observation times. The level-1A PGEs then perform geolocation-refinement calculations and conversions of raw data numbers to engineering units. Finally, the level-1A data are grouped into packages,denoted granules, each of which contain the data from a six-minute ob- servation period. The granules are forwarded, along with calibration data,to the Level-1B PGEs for processing into calibrated, geolocated radiance prod- ucts. The Level-2 PGEs, which are not yet operational, are intended to process the level-1B data into temperature and humidity profiles, and other geophysical properties.

Overview
The document is a Software Reporting Form from the Jet Propulsion Laboratory (JPL) at the California Institute of Technology, detailing the dissemination of software developed for NASA projects, particularly related to the Atmospheric Infrared Sounder (AIRS) project. It outlines the requirements and procedures for sharing JPL-developed software with external entities, emphasizing the importance of collaboration with organizations such as NASA, NOAA, and various academic institutions.
Key points include:
-
Dissemination Requirements: The document confirms that there is a mission requirement to disseminate the software, with outstanding requests from government agencies and collaborations expected to extend beyond JPL. A formal Memorandum of Understanding (MOU) exists between JPL and NASA regarding the AIRS project, which includes the transfer of software code.
-
Collaboration and Agreements: The software is intended for use by several external customers, including NASA's Goddard Space Flight Center (GSFC) and NOAA's National Environmental Satellite, Data, and Information Service (NESDIS). The document specifies that JPL-developed software will typically be disseminated through the Open Channel Software Foundation, which has an agreement with Caltech to host JPL software.
-
Software Status and Testing: The software is classified as "mature," indicating that it has undergone extensive testing and is performing nominally. The document mentions that all Level 1 Processing Ground Elements (PGEs) are functioning as intended.
-
Technical Support Package: The document serves as a Technical Support Package (TSP) for the initial processing of infrared spectral data, providing necessary documentation for the software's use and dissemination. It highlights the software's eligibility for publication in NASA Tech Briefs, which aims to share innovations with wider audiences.
-
Contact Information and Resources: The document includes contact details for the NASA Scientific and Technical Information (STI) Program Office, providing avenues for further inquiries and access to additional resources related to aerospace technology.
Overall, the document serves as a comprehensive guide for the approval and dissemination of JPL-developed software, ensuring compliance with NASA's requirements while facilitating collaboration with external partners in the scientific and technological community.
