TPSAS-NF1676L-32668-DND

The Stratospheric Aerosol and Gas Experiment (SAGE) III is a solar occultation instrument installed on the International Space Station (ISS) that has been providing vertically resolved measurements of aerosol extinction, ozone concentrations, and other trace gases. With a legacy going back to the late 1970s, SAGE ozone measurements have been a vital contributor to international ozone assessments and analyses on stratospheric ozone trends. As the newest SAGE instrument, SAGE III/ISS will continue to provide high precision profiles of ozone that will help determine if the Montreal Protocol has been successful in enabling the recovery of the ozone layer. However, as is a necessary step for all new instruments, a rigorous validation of the data quality is required to determine if the data is sufficient for incorporation into trend analyses. Herein we discuss an initial evaluation of the data quality of vertical profiles of ozone with a focus on internal consistency for the first validation version (v5.1) derived from SAGE III/ISS measurements.

Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS) Newly Released V5.2 Validation of Ozone and Water Vapor Data

The Stratospheric Aerosol and Gas Experiment III (SAGE III) instrument installed on the International Space Station (ISS) has completed over three and a half years of data collection and production of science data products. The SAGE III/ISS is a solar and lunar occultation instrument that scans the light from the Sun and Moon through the limb of the Earth’s atmosphere to produce vertical profiles of aerosol, ozone, water vapor, and other trace gases. It continues the legacy of previous SAGE instruments dating back to the 1970s to provide data continuity of stratospheric constituents critical for assessing trends in the ozone layer. This presentation shows the validation results of comparing SAGE III/ISS ozone and water vapor vertical profiles from the newly released v5.2 science product with those of in situ and satellite data .

Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS) Validation of the Latest Version 5.2 Data Products

The Stratospheric Aerosol and Gas Experiment III (SAGE III) instrument installed on the International Space Station (ISS) has completed over three and a half years of data collection and production of science data products. The SAGE III/ISS is a solar and lunar occultation instrument that scans the light from the Sun and Moon through the limb of the Earth’s atmosphere to produce vertical profiles of aerosol, ozone, water vapor, and other trace gases. It continues the legacy of previous SAGE instruments dating back to the 1970s to provide data continuity of stratospheric constituents critical for assessing trends in the ozone layer. This presentation shows the improvements to the SAGE water vapor product with the release of the newest data version. It also focuses on validation by comparing SAGE III/ISS v5.2 ozone and water vapor vertical profiles with those of in situ and satellite data.

Evaluating the SAGE III/ISS Version 5.2 Water Vapor Retrieval in the Presence of Aerosol Loading

The Stratospheric Aerosol and Gas Experiment operating on the International Space Station (SAGE III/ISS) is an occultation instrument that retrieves aerosol extinction and ozone, water vapor, and other trace gas concentrations. Water vapor in the stratosphere plays a role in ozone depletion and global temperature regulation making it an important species to monitor. The SAGE III/ISS instrument provides high quality, vertically resolved profiles of water vapor throughout the stratosphere and upper troposphere. In previous versions of SAGE water vapor products, a dry bias was noted in comparison to other satellite retrievals in the presence of elevated aerosol optical depth. Several updates for the version 5.2 water vapor algorithm will be presented and compared with previous versions of the data and other satellite products during different periods of aerosol loading.

SAGE III/ISS Validation of Ozone and Water Vapor V5.2 Data Using Collocated Balloon-Borne Measurements

The Stratospheric Aerosol and Gas Experiment III (SAGE III) instrument installed on the International Space Station (ISS) has completed nearly four years of data collection and production of science data products. The SAGE III/ISS is a solar and lunar occultation instrument that scans the light from the Sun and Moon through the limb of the Earth’s atmosphere to produce vertical profiles of aerosol, ozone, water vapor, and other trace gases. It continues the legacy of previous SAGE instruments dating back to the 1970s to provide data continuity of stratospheric constituents critical for assessing trends in the ozone layer. This presentation shows the validation results of comparing SAGE III/ISS ozone and water vapor vertical profiles from the newly released v5.2 science product with those of balloon launched ozonesonde and frost point hygrometer measurements and satellite data from the Microwave Limb Sounder.
