Summary
• Science highlights in key areas:
Carbon cycle and climate gases
Air quality
Tropospheric composition and climate
Stratospheric ozone depletion
• Power of space missions demonstrated in atmospheric science but much remains to be done.
• Close working with field campaigns and models – integrated Earth System Science
• New species, higher spatial resolution
• Challenges to come:
bridging the temporal gap
Maximum information for the near-surface atmosphere
Integrated nadir and limb observations
