SAGE III on ISS SAGE III on ISS - SAGE III on the International Space Station (ISS)

      The SAGE III instrument is used to study ozone, a gas found in the upper atmosphere that acts as Earth’s sunscreen. More than 25 years ago, scientists realized there was a problem with Earth’s thin, 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. Instead of flying on an un-manned satellite, SAGE III will be mounted to the ISS where it will operate alongside experiments from all over the world in the space-based laboratory.

      The SAGE III mission provided accurate, long-term measurements of ozone, aerosols, water vapor and other key parameters of the Earth's atmosphere. These observations are crucial for providing a better understanding of how natural processes and human activities may influence our climate.


SAGE II Logo SAGE II - Stratospheric Aerosols and Gas Experiment II

      The SAGE II mission provided the scientific community with a long-term, global depiction of the distribution of aerosol, ozone, water vapor, and nitrogen dioxide. The data provided unique and crucial input to the understanding of global, seasonal to inter-annual variability in climate and, in particular, trends in stratospheric ozone.

      The Halogen Occultation Experiment (HALOE) was launched on the Upper Atmosphere Research Satellite (UARS) spacecraft September 12, 1991. The experiment used solar occultation to measure vertical profiles of ozone, hydrogen chloride, hydrogen fluoride, methane, water, nitric oxide, nitrogen dioxide, Aerosol Extinction, Aerosol Surface and Temperature versus pressure with an instantaneous field of view of 1.6 km at the earth limb.

      The scientific goal of the SABER project is to explore the mesosphere and lower thermosphere globally and achieve a major improvement in our understanding of the fundamental processes governing the energetics, chemistry, dynamics and transport of the atmospheric region extending from 60 km to 180 km. SABER is one of four instruments on NASA's TIMED Mission.
