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 Constellation Architecture For Monitoring Carbon Dioxide And Methane From Space

This white paper defines a global architecture for monitoring atmospheric CO2 and CH4 concentrations and their natural and anthropogenic fluxes from space to (i) reduce uncertainty of national emission inventory reporting, identify additional emission reduction opportunities and provide nations with timely and quantified guidance on progress towards their emission reduction strategies and pledges; and (ii) track changes in the natural carbon cycle caused by human activities and climate variations.

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.
