The Stratospheric Aerosol and Gas Experiment, SAGE, is a series of instruments designed by NASA to observe stratospheric ozone, aerosols, and water vapor from space. In the mid-1980s, scientists realized there was a problem with Earth’s protective coat of ozone...it was thinning. The SAGE family of instruments was pivotal in making accurate measurements of the amount of ozone loss in Earth’s atmosphere and helped leaders around the world institute an international treaty banning products containing harmful chemicals that destroy stratospheric ozone. SAGE is a key part of NASA’s mission to provide crucial, long-term measurements that will help humans better understand and care for Earth’s atmosphere.
The 3rd cohort of SAGE III/ISS Science Team selections have been made from proposals submitted to the NASA ROSES 2023 A.30 solicitation. Total funding of the 10 investigations selected is approximately $4.8 million, over a period of three years, to begin by mid-year 2024. The range of topics touch all the current occultation science products […]
Stratospheric aerosol plays an important role in chemistry and climate. Space-based observations of their optical properties have been key elements of the study of the effects of major volcanic and extreme fire events. To aid users of SAGE III/ISS Level 2 aerosol data, the mission is releasing a Level 2 aerosol auxiliary product that identifies […]
On September 12 & 13, 2023, the Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS) held its sixth annual science team meeting. This year it was hosted by ROSES science team PI Dr. Hsiang Jui (Ray) Wang of the School of Earth and Atmospheric Sciences at the Georgia Institute of […]
Along with the recent release of the Stratospheric Aerosol and Gas Experiment (SAGE) III / International Space Station (ISS) v5.3 data, the mission is debuting a portal on the SAGE website for public viewing level 2 solar data products: SAGE III/ISS Level 2 Quicklook Browse Images (nasa.gov). The new tool provides a quick and easy […]
The newest version of SAGE III/ISS science data products are now publicly available at the NASA Atmospheric Science Data Center (ASDC). This new version (v5.3) replaces the previous version (5.2) and is the version for forward processing, but prior versions will still be available from ASDC. Several improvements are realized in v5.3. The most notable […]
A Research Opportunities in Space and Earth Sciences (ROSES) call was put out on NASA’s Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES) seeking proposals for members of the SAGE III/ISS Science Team. NASA’s goal of understanding the composition of Earth’s atmosphere and changes that are taking place is furthered by this research opportunity […]
In July, purple and pink hues painted the Antarctica and New Zealand skies — likely the result of atmospheric particles called aerosols that belched into the stratosphere in January during the eruption of the Hunga Tonga-Hunga Ha’apai volcano. Aerosols from eruptions, and extreme wildfires, can remain in the stratosphere for months to years traveling around the […]
A NASA student research program recently took to the stratosphere to make ozone measurements that coincided with events from the Stratospheric Aerosol and Gas Experiment (SAGE) III on the International Space Station (ISS), an instrument developed at NASA’s Langley Research Center in Hampton, Virginia. NASA’s Student Airborne Research Program (SARP) is an eight week summer […]
NASA commemorates Asian American, Native Hawaiian and Pacific Islander (AANHPI) Heritage Month each May to celebrate the achievements of employees of AANHPI descent. Daniel Mangosing, a software release administrator and web developer at NASA’s Langley Research Center in Hampton, Virginia, proudly celebrates his family’s Filipino heritage. While his parents were born and raised in a […]
