Atmospheric Chemistry, Carbon Cycle and Climate (AC4)
AC4 is a competitive research program that incorporates research on atmospheric chemistry and the carbon cycle. In collaboration with the NOAA Laboratories and the academic community, the AC4 program supports research to determine the processes governing atmospheric concentrations of trace gases and aerosols in the context of the Earth System. The program aims to contribute a process-level understanding of the Earth System through observation, modeling, analysis, and field studies to support the development and improvement of models, and to inform carbon and air pollution management efforts.
NOAA, NASA, and commercial partners will work together to oversee the planning, development, launch, testing, and operation of a new satellite air quality instrument to support climate and atmospheric chemistry research and mitigation.
