24/6/05Dr. J.J. Remedios, EOEP review, 27/6/ 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
