Atmospheric Composition

The Atmospheric Composition Virtual Constellation (AC-VC) goal is to collect and deliver data to improve monitoring, assessment, and predictive capabilities for changes in the ozone layer, air quality, and climate forcing associated with changes in the environment through coordination of existing and future international space assets.


A Geostationary Satellite Constellation for Observing Global Air Quality: An International Path Forward (2011)

There are currently three missions in development that make observations relevant to our understanding of air quality and climate change from geostationary orbits. This white paper outlines our recommendations, developed in consultation with the broader air quality research community, on how to facilitate cross-agency collaboration and maximize the benefits of these observations to the research and applications communities.
