Members of the SAGE III/ISS mission team attended the American Geophysical Union (AGU) Fall Meeting from December 10th – 14th, 2018 in Washington, D.C. Conference visitors were able to experience the SAGE III instrument installed on the exterior of the International Space Station through a virtual reality demonstration. SAGE III Program Scientist, Dr. Richard Eckman, gave […]
SAGE III Science Challenges Aboard the ISS
Operating an occultation science instrument aboard a manned, frequently visited spacecraft the size of a football field poses many challenges to data collection and quality. The Stratospheric Aerosol and Gas Experiment (SAGE) III instrument, currently on board the International Space Station (ISS), is equipped with the tools necessary to mitigate and control these challenges. Dave […]
Langley Research Center Former Scientist Awarded Prestigious Medal
Retired SAGE III Project Scientist, Dr. Joseph Zawodny, received the NASA Distinguished Service Medal on August 2. He was awarded for his “Sustained, distinguished contributions to an increased scientific understanding of the Earth’s upper atmosphere.” The Distinguished Service Medal is the most prestigious honor award, approved by the NASA administrator, given to a government employee […]
SAGE III/ISS Science Team Assembled
The SAGE III/ISS mission has assembled its science team members! The individuals on this team from a variety of diverse institutions will conduct studies using the data from the SAGE III instrument to help us better understand the composition of Earth’s atmosphere and how it’s changing. These ten individuals, selected by competitive solicitation, will provide […]
SAGE III/ISS Science Data Validation Efforts Begin
The Stratospheric Aerosol and Gas Experiment III (SAGE III), a NASA Langley Research Center-led mission, was launched on February 19, 2017 and installed on the International Space Station (ISS) during a 10-day robotic operation. Since March 2017, the instrument has been measuring and collecting data on the Earth’s sunscreen, stratospheric ozone, as well as other […]
SAGE III/IV Presented at Science Mission Directorate Monthly Science Review
Members of the SAGE team attended the February Science Mission Directorate (SMD) Monthly Status Review at NASA Headquarters to present an overview and status of SAGE III/ISS and SAGE IV to the Science Mission Directorate. LaRC Center Director, Dr. Dave Bowles, was in attendance to introduce the SAGE team. The SAGE III/ISS portion of the talk […]
SAGE III/ISS Lunar Data Release
The first set of lunar data collected from the Stratospheric Aerosol and Gas Experiment III (SAGE III), a NASA instrument that launched to the International Space Station (ISS) in February 2017, is now available for public use. The data is available through the Atmospheric Science Data Center and includes measurements of ozone and nitrogen trioxide. […]
SAGE III/ISS Observations of the August 2017 British Columbia Wildfires
A pyrocumulus cloud is formed by extreme heating of the air near the earth’s surface. Forest fires can induce the formation process of this type of cloud. The plot below shows an enhancement in the aerosol extinction coefficient detected by the SAGE III/ISS instrument between July 2017 and November 2017, following the enormous pyrocumulus event […]
SAGE III/ISS Initial Data Release for Public Use
The first wave of atmospheric data from SAGE III/ISS is now available for public use through NASA’s Atmospheric Science Data Center. The data was collected from June 2017 to August 2017 and includes measurements of ozone, aerosols and nitrogen dioxide. SAGE III scientists are seeking feedback on this initial data from the international atmospheric science […]
