Description

g3blmnc_52 is the Stratospheric Aerosol and Gas Experiment III (SAGE III) on the International Space Station (ISS) (SAGE III/ISS) Level 2 Monthly Lunar Event Species Profiles (NetCDF) V052 data product. It contains all the species products for a month of lunar events (the last day of each month is omitted) . SAGE III was Launched on February 19, 2017 on a SpaceX Falcon 9 from Kennedy Space Center, SAGE III-ISS is the second instrument from the SAGE III project, externally mounted on the ISS. This ISS-based instrument uses a technique known as occultation, which involves looking at the light from the Sun or Moon as it passes through Earth's atmosphere at the edge, or limb, of the planet to provide long-term monitoring of ozone vertical profiles of the stratosphere and mesosphere. The data provided by SAGE III-ISS includes key components of atmospheric composition and their long-term variability, focusing on the study of aerosols, chlorine dioxide, clouds, nitrogen dioxide, nitrogen trioxide, pressure and temperature, and water vapor. SAGE data has historically been used by the World Meteorological Organization to inform their periodic assessments of ozone depletion. These new observations from the International Space Station will continue the SAGE team's contributions to ongoing scientific understanding of the Earth's atmosphere.

Starting with the events on May 31, 2022, the version number reported in the data products is incremented from 5.20 to 5.21. The monthly product filenames will remain the same for this update. This change reflects an upgrade of the operating system and software compilers used to generate the products. While the Level 1 and Level 2 algorithms remain the same, the underlying upgrades introduce perturbations to the processing stream which manifest as small product differences between the two versions. These differences have been determined to occur without bias or trend, and at magnitudes smaller than reported uncertainty for the vast majority of data points.
