Gases high in the air, measured by moonlight (SAGE III)

SAGE III/ISS L2 Lunar Event Species Profiles (Native) V006
atmosphere NASA LARC_CLOUD Level 2 active Binary
In plain English

What it measures. Vertical profiles of various atmospheric gases and aerosols high in the atmosphere for a single moonlight observation, including ozone, nitrogen gases, water vapor, pressure, and temperature.

How it's made. Measured by the SAGE III instrument on the International Space Station, which watches moonlight pass through the edge of Earth's atmosphere to tease apart what is in the air at different heights.

How & where you'd use it. Supports long-term monitoring of the ozone layer and atmospheric composition, contributing to international assessments of ozone depletion.

Official description

g3blspb_6 is the Stratospheric Aerosol and Gas Experiment III (SAGE III) on the International Space Station (ISS) (SAGE III/ISS) Level 2 Lunar Event Species Profiles (Native) V06 data product. It contains all the species products for a single lunar event. 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.
