Aura MLS Product Generation Software (MLSPGS) for Level 1 and Level 2

Aura MLS Product Generation Software (MLSPGS) for Level 1 and Level 2, covering v1 through the v06.03 release. This code and limited associated documentation herein (more documentation is elsewhere) has been developed for the Aura Microwave Limb Sounder project to produce daily calibrated radiance and engineering (Level 1) and geophysical data along the measurement footprint (Level 2) data products. It includes release for near real-time (NRT) products. More information on Aura MLS Additional information can be found at: Waters, J.W. et al., "The Earth Observing System Microwave Limb Sounder (EOS MLS) on the Aura satellite," IEEE Trans. Geosci. Remote Sensing 44, no. 5, doi:10.1109/TGRS.2006.873771, May 2006. Function and purpose of the software The intent of this software is to, on a routine basis, process the raw telemetry ("Level 0" data) from the MLS instrument and generate higher level data products for use in atmospheric science research. The vast majority of the MLS-based atmospheric science research derives from the "Level 2" data, which are vertical profiles of atmospheric composition and other data products along the orbit/measurement track. These are derived from "Level 1" data, being calibrated microwave limb radiances (and supporting engineering telemetry). Additional information on data processing levels can be found on the NASA Earthdata website. In addition to its use for routine data production, this software can be configured to perform other tasks, including those needed for testing (e.g., generating simulated Level 1 datasets from a known Level 2 dataset, pre-computing some look-up-table-like terms used in the Level 2 processing). In addition to the Level 1 and Level 2 processing software, smaller programs provide additional support.
