• SAGE III on ISS is a directed climate continuity mission
• Mission objective is to obtain climate quality science data from
the ISS
– Inclined orbit of 51.6° is ideal for SAGE III measurements
• Baseline Mission Life is 3 years / Threshold is 1 year
– Planning includes possibility of 2020 extended mission
• Access to space is provided by Space X Falcon 6
• Mission leverages existing flight hardware
– SAGE III Instrument
– Hexapod Pointing System
– ExPRESS Pallet Adaptor
SAGE III Mission Context
National Oceanic and Atmospheric Administration Cooperative Remote Sensing Science and Technology Center
• NEED – enhance our understanding of ozone recovery and climate change processes in the upper atmosphere
• HOW – monitor the vertical distribution of aerosols, ozone, and other trace gases in the Earth’s stratosphere and troposphere
SAGE III Science Objectives
Parameters and processes that control ozone.
SAGE III on ISS provides data to:
Assess the recovery in the distribution of ozone
Extend aerosol measurement records needed for climate and ozone models
Gain further insight into key processes contributing to ozone and aerosol variability
National Oceanic and Atmospheric Administration Cooperative Remote Sensing Science and Technology Center
• Assess the scientific and data usage approaches critical to achieving the goals of the SAGE III on ISS mission as outlined in NASA's Climate Initiative

SAM II/SAGE/Lidar Science Successes
Near global O3, aerosol, cloud, and H2O stratospheric and upper tropospheric profiles, and NO2 mid-to-upper stratospheric profiles, with 1km vertical resolution, contributing to:
1) an understanding of the effects of volcanic aerosols on radiative forcing, ozone depletion, stratospheric temperature change, aircraft structure degradation and possibly increasing cirrus clouds;
2) the determination of aerosol, ozone and water vapor climatologies;
3) the determination of ozone and aerosol trends;
4) the discovery of upper tropospheric aerosol layers from biomass burning in pristine locations;
