request to remove GCMD platform keyword "SAGE-III"

SAGE-III is listed as a platform, see https://gcmd.earthdata.nasa.gov/KeywordViewer/scheme/all/c7063bba-13bf-45e1-be70-7499be35d304?gtm_keyword=SAGE-III&gtm_scheme=platforms.

SAGE III (without a dash) is an instrument that flew on two platforms, ISS and Meteor-3M. There is no such platform as "SAGE-III". Please delete this keyword.

Also, its description,
"The newest SAGE mission, SAGE III on ISS, is scheduled to launch in 2014. Plans include sending a copy of the SAGE III instrument to the International Space Station aboard a commercial Space X flight. SAGE III was a fourth generation, satellite-borne instrument and a crucial element in NASA's Earth Observing System (EOS) . The instrument was launched on the Russian Meteor-3M spacecraft in December 2001. The Meteor-3M mission, along with the SAGE III mission, was terminated on March 6, 2006, because of a power supply system failure resulting in loss of communication with the satellite. The SAGE III mission enhanced our understanding of natural and human-derived atmospheric processes by providing accurate measurements of the vertical structure of aerosols, ozone, water vapor, and other important trace gases in the upper troposphere and stratosphere. Human-derived changes in climate and ozone threaten the health of our planet. They also threaten global economic development and the use of new technologies like high-speed aircraft. By understanding the effect of human activities on the atmosphere, national and international leaders can make informed policy that mitigates or prepares for future climate change. The SAGE III-Meteor-3M Version 3 revised data set, which includes improvements to solar ozone, nitrogen dioxide and aerosol extinction products, is publicly available at NASA Langley's Atmospheric Science Data Center . The data set also includes the release of a cloud presence",
clearly supports this point.
